Abstract

In this paper, we improve the conventional iterative soft interference cancellation by introducing the partial cancellation technique and minimum mean square error (MMSE) multiuser detection technique in an uplink turbo-coded multicarrier code division multiple access (MC-CDMA) system. The performance of our proposed receiver is evaluated in Rayleigh multipath fading channel by using computer simulation. Simulation results demonstrate the advantages of the proposed technique over the conventional technique.
