【Abstract】 The effect of Multi-Address Interference(MAI) on the new generation of large capacity and high-speed CDMA communication system is studied in this paper . The receiving model of the system in synchronal AWGN channel are discussed, and the principles and characteristics of some multiuser detection methods are compared. A new algorithm, multiple-stage correlated compensation method for spatial-temporal joint detection is introduced.更多还原
