摘要
多用户检测技术是码分多址系统中解决多址干扰的关键技术.在介绍多用户检测技术原理的基础上,对现有一些主要算法的性能、特点和不足进行了分析,并展望了该技术的发展方向.
The multi- user detection is a key technique to solve the problem of MAI existing in DS- CDMA system. Based on the introduction of the principle of MUD, this paper made the analysis on the nature, features and shortages of the existing algorithms about MUD, and pointed out the future development of MUD.
