Mr Hao Xu
Dr Vikas Kukshya
Mr Theodore Rappaport
Mobile and Portable Radio Research Group, Virginia Tech

This paper presents measurement results and models for 60 GHz channels.A total of 33 locations in eight different environments are measured at Virginia Tech.Multipath components are resolved in time by using a sliding correlator with 10 ns resolution, and in space by spinning a directional antenna with $7^\circ$ half power beamwidth.Power delay profiles (PDP) and power angle profiles (PAP) are measured in various indoor and short-range outdoor environments.PDP records temporal power distribution over multipath time-of-arrival (TOA), and PAP records spatial power distribution over multipath angle-of-arrival (AOA).Detailed multipath structure is retrieved from PDPs and PAPs, and compared with site-specific environments.Results show strong correlation between the propagation environments and multipath structure.From the recorded 8,848 wideband PDPs and 94 PAPs, received signal power, statistical TOA and AOA parameters are estimated.The high resolution measurements provide great insights into millimeter-wave channel and basis for advanced space-time channel modeling and ray tracing developments.The measured statistical TOA and AOA paramenters also present pragmatic values for broadband wireless system design over 60 GHz short range channels.

Paper 2.1.3.1 Impact of Human Shadowing on Temporal Variation of Broadband Indoor Radio Channel Characteristics and System Performance
Mr.Pejman Hafezi
Dr.Andy Nix
Dr.Mark Beach
University Of Bristol

Results of a comprehensive campaign of measurement to study the effect of moving people on the temporal variation of 5GHz indoor radio propagation characteristics are presented.The measurements consider the impact of various shadowing conditions on the fundamental channel parameters such as received signal strength, RMS delay spread and K-Factor as well as the effects on the quality of a digital transmission link in terms of Bit Error Rate for a multi-rate single carrier QPSK modem.Impact of directional antennas at one or both ends of the link are also studied.It is shown that shadowing significantly increases the short time variations of the channel characteristics, which subsequently impairs the performance of the digital system operating under such conditions.The results provide much needed information for more accurate modelling of practical indoor radio channels.

At UHF and above, shadowing effects caused by the movement of personnel become significant in short-range indoor radio channels.This paper examines pedestrian-induced fading characteristics at key frequencies within the microwave band; consideration is given to the effects of wave obstruction by the human body - reflection, diffraction and transmission. Fading profiles are reported for a point-to-point link in a 150 m-sq open-plan environment.Irrespective of frequency, received power levels fluctuated by 33 dB and fading was flat with a bandwidth of less than 2 Hz.

Paper 2.1.3.3 Monte Carlo Simulation of Delay and Angle Spread in Different Building Environments
Mr Cheolhang Cheon
Mr.Henry Bertoni
Mr.George Liang
Polytechnic University

Advance radio system designs have been proposed that are intended to overcome or take advantage of the impairments of the radio channel caused by multipath effects in urban environments.The design of such systems and their evaluation requires knowledge of higher order channel statistics.For example, the design of smart antenna systems requires knowledge of the delay spread and angle spread in the environment where the system is to function.The delay and angle spreads have been measured at individual locations in a few cities.However, it is not clear if the measured results are widely applicable to other building environments.To overcome this limitation, we have used the 3D ray tracing code, called the VPL method, to simulate channel statistics.Our goal is to relate the variation of statistical properties of the radio channel to the statistics of the building environment, and to the geometry of the radio link.Simulations have been run to find the influence of the statistical parameters describing the building distribution and on delay and angular spreads.

Paper 2.1.3.4 Detailed radio imaging of buildings at 2.4 GHz
Mr M J Mughal
Dr A.M.Street
Dr C.C.Constantinou
The University of Birmingham

In the following study, we resolve a radio image reflected off a building to a resolution of 4-5 m, and identify contributions to the channel impulse response with detailed geometrical features of the environment that correspond to individual ray-optical interactions.We finally discuss briefly the validity of the common assumptions made by ray-tracing tools in the light of these results.The radio imaging measurement system, used for measurements, was based upon the vector network analyzer (VNA) technique in which the receive antennas were scanned over a volume to form a synthetic aperture for multipath angle-of-arrival (AoA) determination.The frequency domain measurements were converted into the delay domain using conventional fast Fourier transform techniques.The resulting CIRs were time gated and the AoA as a function of delay was determined using robust matched filtering techniques.The measurements presented in this paper used a centre frequency of 2.440 GHz with a bandwidth of 80 MHz giving multipath delay resolution on the order of 4-5 m.The synthetic aperture was configured to provide azimuth angular resolution of the order of 10o, and elevation resolution of the order of 30 o.

Paper 2.1.3.5 The Bluetooth Channel
Dr Gert F Pedersen
Dr Patrick Eggers
Aalborg University

The Bluetooth channel is new in the sense that it is very short range and communication between relatively slowly moving or stationary terminals.Channel measurements for typical Bluetooth channels have been made with a four channel sounder.One end of the link is a two antenna card in a notebook used for transmit whereas the reciving terminal was a small devise with two antennas which was placed in different orientations and even carried by a person.The results shows that low correlations can be obtained between the two antennas.Furthermore that the coherence bandwidth is higher than the total Bluetooth bandwidth in 20 to 50% of the time.This means that the frequency hopping included in the system does only combat interference and not suppres multipath fading.

Paper 2.1.4.1 Closed-loop transmit diversity techniques for multi-element transceivers
Ari Hottinen
Olav Tirkkonen
Risto Wichman Nokia Research Center

The transmit diversity concept adopted for the FDD mode of the third generation WCDMA system in 3G standardization is currently optimized for the case where there are two transmitting elements in the base station.Then, the open-loop mode applies a space-time block code for two transmit antennas, and the closed-loop mode has two sub-modes which both use feedback-based weight to approximate matched beamforming.In this paper we propose backward compatible generalizations to the feedback modes which are applicable in the presence of an $M$-element array.Different concepts that reduce the capacity of the feedback signaling are introduced.

Paper 2.1.4.2 Performance of Downlink Nulling in Combined Packet/Circuit Switched Systems
Mr Klaus Hugl
Prof Ernst Bonek
Institut fuer Nachrichtentechnik, Tech.Univ.Wien

Downlink beamforming is the limiting factor in the application of adaptive antennas in cellular mobile communication systems.Directing nulls of the antenna pattern to active mobiles in the downlink will be impossible in the case of packet data transmission (e.g.GPRS/EDGE).But in the evolution of 2nd generation mobile communication systems packet switched data transmission and circuit switched speech communication will be used in parallel.We will show by link level simulations, that also in combined packet/circuit switched mobile communication systems smooth downlink interferer nulling will lead to performance and capacity improvement.The interference suppression due to smooth nulling of the circuit switched users outperform by far the loss in the antenna gain and therefore the interference increase for the packet data users.

Paper 2.1.4.4 Link-Optimal BLAST Processing with Multiple-Access Interference
Dr Angel Lozano
Dr Farrokh Farrokhi
Dr Gerard Foschini
Lucent Technologies

Recent information theory results have demonstrated the enormous capacity potential of wireless communication systems with multiple transmit and receive antennas.To exploit this potential, a number of layered space-time (BLAST) architectures have been proposed which transmit parallel data streams, simultaneously and in the same frequency band, in a multiple-input multiple-output fashion.With sufficient multipath propagation, these different streams can be separated at the receiver.Mostly, these space-time schemes have been studied only in the presence of spatially white noise.In this letter, we present an architecture that is optimal, in the sense of maximizing the link spectral efficiency, in the presence of spatially colored interference.We evaluate this new architecture and compare it, under various propagation conditions, to other adaptive-antenna techniques with equal number of antennas.

Paper 2.2.2.2 Coherent Interference Suppression with an Adaptive Array Using Spatial Affine Projection Algorithm
Ms Yahong Zheng

Carleton University

Conventional adaptive beamforming methods exhibit signal cancellation phenomena when the interferers are highly correlated with the desired signal.In this paper, we propose a new adaptive beamforming algorithm for multiple coherent interference suppression, which utilizes the Affine Projection Algorithm in space domain (SAP).The proposed SAP algorithm outperforms the existing time averaging algorithms with faster convergence and deeper nulls in the beam pattern, because the projection of the SAP algorithm provides additional decorrelation comparing to simply subgrouping. The computational complexity of the SAP algorithm is close to that of the other schemes using the NLMS adaptation algorithm.

Paper 2.2.2.3 Investigation of the trade-off characteristics of beamforming performance in DS-CDMA system
Dr Tae-Gyu Chang
Mr Jae-Hwa Kim
Mr Chong-Yoon Kim
School of Electrical Engineering, ChungAng University

This paper presents the analytic derivations and the operation simulations of the SINR behavior when a linear array antenna is accommodated into the cellular CDMA basestation with beamforming(BF) algorithms.The roles of the two major performance-effecting design factors, i.e., the direction selectivity of an array antenna and the direction-of- arrival (DOA) precision in BF algorithm, are investigated not only in view of the SINR itself but also in view of the BF algorithm's robustness to the erroneous factors of spatial scattering of radio waves and DOA error.It is confirmed from this study that there exists a trade-off characteristics between the SINR and the robustness with respect to the above two design factors.The trade-off characteristics can be capitalized to obtain an economic means of BF implementation for cellular CDMA system which does not severely deteriorate SINR performance while ensuring its robustness to the erroneous factors.

Paper 2.2.2.5 Non-stationary Interference Exciser in Smart Antenna Systems Using an Adaptive Gabor Expansion
Mr.Jaehak Chung
Mr.Sang-Youb Kim
Dr.Edward Powers
The University of Texas at Austin

Since smart antenna systems which employ spread spectrum methods are sensitive to a time-correlated non-stationary jammer, precise excision of the jammer noise is required.To remove this non-stationary jammer, we propose, in this paper, a new adaptive Gabor noise exciser, which can track optimally the change of the time and frequency densities of the jammer.To find the optimum time-frequency Gabor expansion for the received signal, we utilize the optimum projection method.In the time-frequency Gabor domain, we remove the non-stationary jammer, and reconstruct the jammer-free signal from the remining Gabor coefficients.This approach exhibits better performance than the non-optimized Gabor transform exciser.

Current research efforts for next generation mobile systems are focusing heavily on advanced antenna arrays to improve system capacity.To this end, algorithms are being developed which calculate complex weighting factors used for beam shaping and steering.These algorithms require that the relative phase between receiver channels be stationary.However, effects such as cable heating and oscillator phase noise can cause fluctuations.To compensate for relative phase stability between receiver channels a reference channel can be used.This paper investigates parameters which determine the phase stability of a system and the use of a reference channel.It also presents data collected using a multichannel broadband receiver developed for advanced antenna algorithm testing.Phase data collected in the laboratory is contrasted with field data using a remote reference at 1.92 GHz.Results are analyzed and compared with theory.

Analytical and simulation analysis is developed to study the impact on spectral efficiency when the adaptive antennas at the base stations in a cellular network maximize trunking efficiency.In order to maximize trunking efficiency, the adaptive antenna array is used to extend the coverage range over an omni directional antenna.The extension in range is then used to optimize the base station to mobile assignment in order to minimize the number of mobiles blocked.Based on simulation results an increase in system capacity by 2 to 4 times may be achieved using this approach.

Paper 2.2.3.4 Optimum element arrangement of adaptive base station antennas for SDMA in circular cell

Nippon Telegraph and Telephone Corporation

Space division multiple access (SDMA), which enableenables multiple users to use a communication channel by utilizing adaptive base station antennas, is an attractive candidate for enlarging the channel capacity of mobile communication systems.This paper derives the mathematical formula of an average squared spatial correlation (ASSC) that determines the optimum element arrangement of the adaptive base station antennas for the SDMA, which discriminates between two users in a circular zone.The optimum array configurations for a linear array and a circular array are clarified.As the results, the optimum inter-element spacing for linear array appears at 0.4-wavelength and approximately 0.5-wavelength intervals.The optimum spacing does not depend on the number of elements.The optimum array radius for the triangular array (N = 3) appears at 0.2-wavelength and approximately 0.3-wavelength intervals.When the number of elements is increased, the interval obtaining the minimum ASSC becomes long.The optimum radii are 0.96 and 1.27 wavelength for 4 and 8 element arrays, respectively when the array radius is less than 1.5 wavelength.

Two new algorithms are proposed for downlink beamforming in FDD DS-CDMA mobile radio by using uplink beamforming weights. One is null constrained (NC) method, which constrains same null positions for both links' beam patterns; the other is frequency calibrated (FC) method, which constrains same main beam's positions for both patterns.These algorithms are simple in implementation and computation.Simulations have shown that the new algorithms can support much higher system capacity than traditional DOA-based approaches.

Paper 2.2.4.4 Soft Handoffs in Code Division Multiple Access Systems with Smart Antenna Arrays
Mr.David Hastings
Dr.Hyuck Kwon
Wichita State University

Soft Handoffs are an important part of Code Division Multiple Access (CDMA) systems.With the increasing interest in smart antenna systems, the issue of soft handoff needs to be addressed for CDMA systems with smart antenna systems.This paper presents an analysis of smart antenna coverage and soft handoffs in a CDMA system.This paper will also show the relevance of soft handoffs on the system capacity.It is well known that smart antennas improve the capacity of a CDMA system by reducing interference at the receiver.But the soft handoff region increases due to the non-uniform receiver gain in smart antennas.These two issues combined with a limited number of forward link channels turns a CDMA system from a reverse link limited system to a forward link limited system.However, with appropriate cell sector orientation, the soft handoff region coverage can be optimized while maintaining an appropriate margin.This will then optimize the soft handoff region size and t! he overall system capacity.It will be shown that cell sector orientation, with smart antennas, closely approximates the Interleaved Narrow Beam Tri-sector Cell (INBTC) architecture.

In this paper, a novel multiuser technique is presented for directly determining the total transmitted signal of one base station in order to serve a number of mobile stations (MSs).Each MS is assumed to use a single matched filter (MF) only, which is matched to a MS specific spreading code.Based on the exact of approximate knowledge of the relevant channel impulse responses, the transmitted signal is chosen this way, to compensate the influence of ISI and MAI at the location of each MS.Consequently the MS specific data symbols can directly be taken from the outputs of the MFs without any necessary equalization.This technique achievs two goals: First, no training sequences are used, thus significantly increasing the data rate and simplifying the receiver structure at the MSs.Second, a single MF is used at each MS, thus requiring no equalization.

A random access scheme suitable for multihop wireless networks is proposed that uses multiple channels and a dynamic channel selection mechanism.Channel selection is based on local measurements of signal power on all the channels.A protocol similar to CSMA/CA (carrier sense multiple access with collision avoidance) is adapted on the chosen channel. The proposed scheme reduces the effect of interference, thereby reducing the probablity of packet collisions.Detailed simulation results are presented showing the effectiveness of the scheme.

An ad-hoc wireless network consists of mobile terminals forming a temporary network without any deployed infrastructure or centralized administration.A general constraint common to many ad-hoc networks lies in the short lifetime of mobile terminal batteries.Hence, energy efficient protocols are needed to reduce the effect of this constraint.In this paper, we propose a MAC algorithm with high energy efficiency for CDMA-based ad-hoc wireless networks.A proposed MAC algorithm is based on scheduling method that informs each terminal when to wake up from sleep mode or when to go to sleep for its power saving.We perform a simulation to evaluate delay, fairness, through, and energy efficiency as metrics of our MAC protocol.It can be used in multimedia classes, military operations, and robot cooperation in inland places.

Paper 2.3.2.5 Extending Earliest-Due-Date Scheduling Algorithms for Wireless Networks with Location-Dependent Errors
Dr.Shiao-Li Tsao

Generalized processor sharing (GPS) and earliest-due-date (EDD) algorithms are two work conserving service disciplines to provide bounded delay and fair scheduling on wired networks.Unfortunately, these algorithms can not be directly applied to wireless networks due to the location-dependent errors in mobile environment.A number of previous studies enhanced GPS-like algorithms to accommodate to the wireless environment.Unlike GPS-like algorithms which guarantee a delay bound based on the weight that is tightly coupled to a reserved service rate, EDD and its extensions such as delay-EDD and jitter-EDD policies allow for the separation of delay, delay-jitters and throughput guarantees for a particular data flow.However, studies of EDD scheduling algorithms on wireless network are almost ignored.In this paper, we explore EDD and delay-EDD policies, and present their extensions.The proposed algorithms can achieve short term and long term fairness, and QoS guarantee! s on wireless networks.

The explosive growth in mobile communications market over the last decade demonstrates the enormous demand for communications mobility.This demand is paralleled by a proliferation of tetherless portable computing devices and a surge in data services usage.Therefore, we are faced with the challenge of incorporating data into networks that were originally designed for voice.In order to jointly carry this extraordinary growth of a wide range of services over the air interface of the mobile radio network, advanced microcellular technology with intelligent channel assignment protocols should be adopted.Microcells are characterised by their massive capacity, low power requirements, equipment miniaturisation, flexible deployment and high spectral efficiency.However, working with microcells results in an unbounded handovers due to the high rate of microcell boundary crossing by active mobile stations (MSs).The current paper introduces a new concept of dynamic length microcellular structure.The highway microcellular mobile radio network is considered as a case study.The microcell length can be designed in order to be adaptable to the number of mobile users in a microcell that is basically dependent on the prevailing vehicular traffic flow.It is, therefore, possible to arrange for the network to accommodate all users roaming in its service area under any traffic situation.This can be arranged by deploying redundant base stations (BSs) on the lamp posts and implementing vehicular traffic sensors along the highway.The BSs are connected by a token passing bus local area network that is controlled by a base station controller (BSC) or a mobile switching center (MSC).The output of the sensor is used as a controlling signal.The controller determines the optimum microcell length according to the traffic flow and transmits a suitable supervisory packet to the appropriate BSs in o! rder to switch on their transceivers with the convenient transmitted power.The layout characteristics of the microcellular structure is addressed and the required cluster size as a function the attainable carrier to interference ratio (CIR) is discussed.In addition, the paper proposes a queuing priority channel assignment protocol suitable for the integration of voice and data traffic on the air interface of a microcellular mobile radio network.As voice calls are time-critical and the interruption of a conversation is unbearable, the strategy aims at minimising this phenomena.The access of a voice call attempt is handled on of a blocked calls cleared basis.Data traffic, on the other hand, are served on a delay basis as the prompt delivery of data is not stringent. Therefore, the strategy satisfies the service quality requirements for both voice and data traffic.A new voice call attempt is allowed access to (Nc =N- Nh) channels out of the N channels assigned to the microcell.A handover voice attempt can access all the N channels of the microcell.Should a voice handover is attempted while all of the N channels being busy, the attempt is allowed to join a queue waiting for a channel in a first come first served basis.I! f the waiting voice handover attempt cannot get a channel prior to link deterioration, the call is forced to terminate.In contrary, an attempt to initiate a data session or to handover a data service when finding all the microcell channels being busy, joins the queue and waits until either a channel becomes available or the MS moves out the current microcell to the next microcell.With this approach, data traffic suffers no blocking but encounters queuing delay.A data session, in this sense, may be
