Abstract

The bit error probability of a code division multiple access (CDMA) system based on direct sequence (DS) spread spectrum (SS) for binary phase shift keying (BPSK) has been investigated using a theoretical model. This investigation has been carried out for a Rician fading radio channel in an indoor environment star connected multiple access radio network. The receiver consists of a multipath combiner. We also have investigated the effect of multi-user interference cancellation on the performance of the system. Computational results are presented for suitable values of Rician parameters in an indoor environment and using Gold codes as spread spectrum codes.
