多用户检测技术及其发展与应用
he Development and Implementation of the Multi-User Detection Technology
第三代移动通信系统采用码分多址(CDMA)方式。由于CDMA系统是一个自干扰系统，存在多址干扰及远近效应，因而限制了系统的容量和性能。多用户检测技术能从根本上消除多址干扰，提高系统的性能。本文主要介绍了多用户检测的思想和分类，并简要介绍了各种多用户检测算法，还提出了多用户检测技术的新发展和在几个具体系统中的应用。
he 3rd generation mobile communication systems use CDMA. As CDMA system is a self-interference system with MAI and Near-far effect, the system capacity is limited. Multi-user Detection can cancel MAI and improve the performance of the system. This paper mainly introduced the theory of multi-user detection and some MUD algorithms, then delivered the recent progress on MUD technology and the application in specific systems.
