Among different multirate access schemes multicode MC-CDMA is attractive for its high performance good flexibility in rate matching and low complexity. However its performance is limited by self-interference SI and multiuser interference MUI . In this paper a zero-forcing successive interference cancellation ZF-SIC receiver is used to mitigate this problem for multicode MC-CDMA. Furthermore optimal power distribution control PDC which minimizes each user s bit error rate BER is considered. Our results show that in correlated Rayleigh fading channels the ZF-SIC receiver integrated with the optimal PDC dramatically improves the performance of the multicode MC-CDMA system in comparison with other receivers proposed in the literature. Moreover the optimal PDC significantly outperforms the PDC based on equal BER criterion particularly under a short-term transmit power constraint. Keywords and phrases multicode multicarrier CDMA zero-forcing successive interference cancellation power distribution control. 1. INTRODUCTION Multicarrier CDMA MC-CDMA .
