摘要 提出了应用于CDMA上行链路多用户检测器中的半盲LSCM_ SUB算法.它首先利用非盲算法消除所有小区内干扰用户的影响,接着再利用LSCM-SUB算法抵消剩余的干扰.仿真实验表明,与盲LSCM算法及解相关算法相比较,该SB-LSCM_ SUB算法的性能明显优于其他几种经典的盲恒模算法及解相关算法. 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.
