Abstract :
The paper investigates the performances of a direct sequence code division multiple access (DS-CDMA) system. This system uses a BPSK modulation for the downlink and a differential BPSK modulation for the uplink. The authors assess the performance of the system over a wideband channel through analytical calculations as well as simulations. They also show that this performance can be greatly enhanced by deploying second or third order space diversity. The minimum diversity order necessary to achieve a given bit error rate is then derived for a system with a given number of users
