CDMA中盲自适应多用户检测算法的研究与分析

Research and analysis of CDMA blind adaptive multiuser detection arithmetic

在传统的自适应检测方法改进的基础上,总结了最新的LMS,RLS,Kalman算法在CDMA多用户检测上的应用。文中给出了三种算法原理及方法,并用Matlab工具进行仿真。在比较三种检测方法的平均信干比和加不同干扰条件下误码率的基础上,得出三种算法的抗干扰性能较好,而Kalman算法表现了最优的性能。

Based on the traditional adaptive multiuser detection method,sum up application of new LMS,RLS,Kalman arithmetics in DS-CDMA Multiuser detection.principles and methods of 3 arithmetics were given and emulation by Matlab.Based on comparing with SIR and errorcode of 3 arrthmetic,Kalman arithmetic show more excellent detection performance.
