This paper analyses the reverse link capacity of a SIR-based power-controlled code-division multiple access (CDMA) system in a multiple-cell environment where the radio channel is affected by multipath Rayleigh fading. Unlike most previous works related to SIR-based power control, the effect of multipath fading is explicitly accounted for and mobiles are assumed to connect to the base station w...

Thomas Eng, A. Chockalingam, Member, IEEE, and Laurence B. Milstein, Fellow, IEEE Abstract— The effect of phase noise on the capacities of coherently demodulated hybrid FDMA/CDMA systems operating over a multipath Rayleigh fading channel is investigated. Using an approximate upper bound on the BER performance which has been derived and presented in a previous paper, the capacities of the FDMA/C...

Novel analytic solutions are derived for integrals that involve the generalizedMarcum -function, exponential functions and arbitrary powers. Simple closed-form expressions are also derived for specific cases of the generic integrals. The offered expressions are both convenient and versatile, which is particularly useful in applications relating to natural sciences and engineering, including wir...

Reliable positioning of cellular users in a mobile environment requires accurate resolving of overlapping multipath components. However, this task is difficult due to fast channel fading conditions and data ill-conditioning, which limit the performance of leastsquares-based techniques. This paper develops two overlapping multipath resolving methods (adaptive and nonadaptive), and shows how the ...

This paper presents a simple formula relating multipath angular spread to small-scale fading statistics. This formula is then applied to nd an approximate spatial cross-correlation function for received voltage envelopes. The analytical approach is compared to 67 cross-correlation functions simulated with non-omnidirectional multipath. The equations in this paper provide insight for applying sp...

The main principle of RAKE receiver is that they exploit multipath propagation by receiving the multipath components of the transmitted signal separately and combining their energies. The complete design, for this purpose, can be segmented into distinct stages or blocks based on their functionality. The incoming data is fed to different fingers after different delays. In each finger the data is...

Linear minimum mean square error (LMMSE) receivers are capable of suppressing multiple access interference and near-far occurrences in a code division multiple access (CDMA) system operating in multipath fading wireless channels. Their relative low complexity makes them suitable for both uplink and downlink receivers. Third generation receivers are mainly based on coherent detection. Carrier fr...

Multipath propagation is a major source of degradation in the performance of conventional PN code tracking loops. The mean-square tracking error of a conventional delay-locked loop (DLL) exhibits an irreducible floor due to the presence of closely spaced multipath components. In this paper, we present a new PN code tracking algorithm that does not suffer from the presence of multipath component...

An effort has been made to illustrate the performance of the Rayleigh fading channel models by using Qual net simulator in terms of Throughput and PDR. A scenario has developed here for the Rayleigh fading channels, with various parameter. The parameters such as data rate and speed of nodes play very important role in the performance analysis and design of the mobile ad-hoc network over the mul...

We propose new detectors for direct-sequence code-division multiple-access (CDMA) signals that outperform known approaches in rapidly fading multipath channels. Multipath compensation in CDMA systems is a problem of significant complexity especially when rapidly fading is afflicting the radio frequency channel. In this work, we depart from typical approaches in search of new kernels that can mo...
