Abstract: The semi-blind LSCM-SUB (SB-LSCM-SUB) algorithm applied in the semi-blind MUD (Multi-user detection) of CDMA is studied.Compared to the blind CM algorithm and the decorrelation algorithm, the proposed semi-blind LSCM-SUB algorithm exhibits better SIR and BER performance, and is more robust when the system is heavily loaded.

Key words: MUD, SB-LSCM-SUB, LSCM-SUB, LSCMA
