一种用于多径衰落信道的盲多用户检测器

A Blind Multiuser Detection in Multipath Fading Channel

将基于递归最小二乘算法的盲多用户检测器与RAKE接收机相结合,提出了一种适用于频率选择性衰落信道下的接收机,叙述了其工作原理和算法,分析了其性能。仿真表明,该接收机无论在收敛性能还是在误码性能上均优于基于Rosen梯度投影的接收机。

By combining RAKE receiver and blind multiuser detection based on a recursive least square(RLS) algorithm, an adaptive receiver which can be used in multipath fading channel is presented. Simulations show that the convergence performance and symbol error performance of the presented RAKE receiver is better than the receiver based on Rosen gradient projection algorithm.
