【Abstract】 To suppress multi-access interference in CDMA system,a new Multi-User Detection(MUD) approach in fading channel based on constant modulus algorithm(CMA)is proposed in this paper.The equivalent discrete receiver signal is modeled and denoted in matrix expression form.Also,the relations between taps of receiver equalizer and equivalent spread spectrum code matrix are deduced.Computer simulation results show that is is effective and feasible.更多还原
