Abstract

The Direct Sequence-Code Division Multiple Access (DS-CDMA), Frequency Hopping-CDMA (FH-CDMA), and Multi Carrier-CDMA (MC-CDMA) are well known wireless communication techniques. However, the comparative bit error rate (BER) performance analysis of these techniques with multi-users in fading channel are lacking in the literature. Hence, in this paper, closed form expressions for BER computation of DS-CDMA, FH-CDMA, and MC-CDMA in Rayleigh fading channel with multi-user's are presented and BER performance of the techniques are evaluated and compared.
