多用户检测算法及其性能分析

Algorithm of multiuser detection and its analysis of performance

首先阐述了多用户检测的现状,并介绍了线性多用户检测算法、判决反馈检测器、盲多用户检测、盲多用户检测的子空间方法等几种主要的多用户检测技术.对几种多用户检测方法进行了误码率仿真分析,最后对多用户检测技术进行了展望.

In this paper,we introduced the actualities of multiuser detection and such technologies as linear multiuser detection,decisionfeedback detector,blind multiuser detection and subspace method for blind multiuser detection.At the same time,the differences between their capabilities were specialized.At the end of the paper,we forcasted the foreground of this kind of technology.
