摘要
多用户干扰是影响 DS- CDMA系统性能及容量的主要因素 ,对几种多用户检测技术进行了分析比较 ,并对其中重要的线性 MMSE检测器进行详细讨论 ,最后指出了目前多用户检测技术存在的问题 ,提出了若干有前途的发展方向。
Multiaccess interference (MAI) is a major factor on the performance and capacity of the DS CDMA system. In this paper,the authors analyze and compare several adaptive multiuser detections for DS CDMA signals, and especially discuss the most important linear MMSE detector in details.And then the authors point out some problems in this technique at present and suggest several ways of promising development.
