Performance of Cellular DS-CDMA Systems Using Distributed Antennas

Abstract

In this contribution we propose and investigate a high-capacity cellular DS-CDMA wireless communications system, where numerous antennas are distributed in the area covered by the system. The bit error rate (BER) performance of the distributed antenna cellular DS-CDMA system is investigated, when transmission pass-loss, lognormal shadowing slow fading and Nakagami-m fast fading are considered. Our investigation and numerical results suggest that the distributed antenna cellular DS-CDMA system constitutes a high power-efficiency wireless system. For utilizing the same set of system parameters, it is capable of providing an extremely higher capacity, than the cellular DS-CDMA system built on the conventional cellular concepts
