Performance of MMSE Multiuser Detection in Cellular DS-CDMA Systems Using Distributed Antennas
In this contribution we propose and investigate a high-capacity cellular direct-sequence code-division multiple-access (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 minimum mean-square error (MMSE) multiuser detection is employed, and when transmission pass-loss, lognormal shadowing slow fading and Nakagami-m fast fading are considered. Our study suggests 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 designed based on the conventional cellular concepts. Furthermore, the proposed distributed antenna cellular system can be operated without having to use power-control.

Abstract

In this contribution we propose and investigate a high-capacity cellular direct-sequence code-division multiple-access (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 minimum mean-square error (MMSE) multiuser detection is employed, and when transmission pass-loss, lognormal shadowing slow fading and Nakagami-m fast fading are considered. Our study suggests 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 designed based on the conventional cellular concepts. Furthermore, the proposed distributed antenna cellular system can be operated without having to use power-control.
