空时MMSE算法与解相关多用户检测器相结合的研究

Research on the Combination of the Space-time MMSE Receiver and the Decorrelating Multiuser Detector

解相关多用户检测是目前CDMA移动通信系统中应用较为广泛的一项接收技术,它的抗远近效应是最佳的,但是其误码性能并未达到最佳,提出了一种将空时MMSE算法与解相关多用户检测联合处理接收信号的方案,经计算机仿真可以看出,这种方案确实对系统的接收性能有一定的改善。

Decorrelating Multiuser Detector is a widely applied technology in CDMA mobile communication system at present and its nearfar restance is optimum, but its bit error rate is not optimum. This paper proposed a method for combining the spacetime MMSE receiver and the decorrelating multiuser detector. As can be seen from the computer simulation, the method can really improve the receiving function of the system.
