TITLE :On Simulation of DS/CDMA Communication Systems AUTHOR :XU Juan
ABSTRACT:In this paper , the bit-error-rate(BER) performance of the asynchronous direct-quence CDMA(DS/CDMA) multiur system in a wireless radio communications environment characterized by Rayleigh multipath fading channels is investigated. Becau of the system complexity,the BER performance of CDMA systems in such an environment is difficult to asss analytically. Monte-Carlo(MC) simulations can offer an alternative performance evaluation tools. But such an alternative is often is often limited by an excessive computational burden.Importance Sampling(IS) is a variance reduction technique which can significantly reduce the computatinal cost r
equired by MC simulations.This paper will describe the basic principles of IS and the BER of DS/CDMA multiur system in Rayleigh multipath fading channels is simulated using MC method and IS technique respectively.Simulation results indicate that IS results and MC results are in clo agreement and that IS simulation can significantly reduce the computational cost required by MC simulation when the RER is very low.new blash
