一种盲自适应随机CDMA多用户检测器

A Blind Adaptive Stochastic Multiuser Detector for CDMA Systems

提出一种盲自适应随机多用户检测器 ,并进行了仿真分析。通过合理地选取时变步长 ,使得算法刚开始时步长取大值以加快收敛速度 ,算法将结束时取小值以减小 NSE(规范化平方误差 )极限值 。

A blind adaptive stochastic multiuser detector for CDMA systems is presented. The simulation results show that by reasonably choosing time varying step size, which takes larger values at the beginning so as to let the convergence be faster and smaller values at the end so as to let the limiting NSE (Normalized Squared Error) be smaller, it can effectively increase the system performance.
