Abstract

This paper investigates the error rate performance of a multi-code DS/CDMA systems using the combination of PN codes and DPSK: differential parallel combinatorial code-division multiple access (DPC/CDMA) systems in Rayleigh fading channels. The bit error rate (BER) are calculated based on the average SNR with the standard Gaussian approximation of the multiple access interference. It is assumed that the explicit and implicit diversity are employed in the receiver. The BER performance of uncoded and coded DPC/CDMA systems are presented, and are compared pared with that of conventional DPSK-DS/CDMA systems
