Abstract
In this paper, we analyze bit error rate performance of a special case of multitone CDMA systems that is Replica MT-CDMA system. It is shown that with the same bandwidth, the Replica MT-CDMA outperforms the conventional system that we name it S/P MT-CDMA. We also propose a low-rate bandwidth efficient channel coding scheme for Replica MT-CDMA that by using it, the coded Replica MT-CDMA system needs the same bandwidth as the uncoded one. In this paper, we compare the proposed low-rate coded and uncoded Replica MT-CDMA systems with S/P MT-CDMA system over uplink Rayleigh fading channel. Our results show that with the same bandwidth, the performance of the coded Replica MT-CDMA system with the proposed channel coding scheme is considerably better than that of both uncoded MT-CDMA systems.
