摘要: 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 GA MUD as well its near-far resistance are a range parameter values. It shown that proposed capable significantly reducing complexity comparison to Verdu's (1998) optimum MUD. For example, when supporting K = 20 users. number likelihood function evaluations reduced by factor 1300.
