【摘要】 多用户信号检测是研究码分多址通信网中多址干扰抑制方法的理论，近年来日益得到人们的重视。本文着重对线性无偏差最小方差（ＬＵＭＶ）多用户信号检测器进行了理论分析，导出了误码率公式及其上下界，给出了ＬＵＭＶ多用户检测器的渐近效率，分析了同步误差对检测器性能的影响，并给出计算机仿真结果。更多还原

【Abstract】 Multiuser signal detection is a theory concerning the multiple access interferences in CDMA networks, which is given more and more attention recently. This paper focuses on the performance analysis of the Linear Unbiased Minimum Variance ( LUMV) multiuser detectors.The error probability formula of the detector, together with its upper and lower bounds, are derived.The asymptotic efficiency is also given. The effect of synchronous error is analysed with computer simulations .更多还原
