TD-SCDMA系统的线性多用户检测算法及性能仿真

Linear Multiuser Detection Algorithm and Simulation of the Performance in TD-SCDMA System

在 TD- SCDMA系统中 ,MAI和远近效应的存在使系统性能受到极大的影响 ,传统的检测器把MAI作为噪声处理 ,不能消除 MAI和远近效应的影响。讨论了在多径瑞利衰落信道下的多用户检测技术中的几种不同的检测算法 ,并对这几种不同的算法进行了仿真和比较。

In TD SCDMA system,the existing of the MAI and ‘far near efficient’ affects the system performance. The conventional detection can't reduce the efficiency of the MAI and ‘far near efficiency’ because MAI is treated as noise. Several linear multiuser detections of in multi path rayleigh channels have been studied,simulated and compared.
