Introduce the Multiuser Detection (MUD) for DS-CDMA system 􀂄 Give two MUD methods for DS-CDMA system –Decorrelating MUD –Subspace MMSE MUD 􀂄 Compare them with traditional decorrelating detection 􀂄 Study the BER vs. S

This paper compares between the BER performance of DS-CDMA, Multicarrier DS-CDMA, and MT-CDMA schemes in a synchronous downlink communication channel.
