A genetic algorithm (GA) assisted multiuser detector (MUD) designed for MC-CDMA is investigated in the context of frequency selective Rayleigh fading channels. The achievable BER performance of the GA assisted MUD as well as its near-far resistance are investigated for a range of parameter values. It is shown that the proposed GA assisted MUD is capable of significantly reducing the complexity in comparison to that of Verdu's (1998) optimum MUD. For example, when supporting K = 20 users. the… CONTINUE READING
