摘　　要：多用户检测算法是码分多址系统中解决多址干扰的关键技术之一,近年来人们对此做了许多研究。现分析了几种典型的多用户检测算法的特性,给出了它们的性能特点。The multiuser detection is one of the key techniques to solve the problem of multiple access interference existing in DS - CDMA system. A lot of work has been done recently in the research on new algorithm of MUD. This paper first gives the comparison of the principle of MUD; then presents the analysis on the characteristics, features and shortages of the existing algorithms about MUD.

关 键 词：码分多址 多址干扰 多用户检测
