摘要
容量无线数字通信系统对多径传输引起的传播恶化很敏感，所以抗多径干扰技术是数字通信中研究的重要课题之一。本文分析了多径干扰的起因，讨论了几种主要的抗多径干扰技术对通信系统性能改善的情况．
The large capacity wireless digital communication systems are inherently sensitive to waveform distortion caused by multipath transmission, therefore the anti-multipath interference technology is one important topic which in the digital communication studies. This paper has analyzed the multipath interference cause, discussed several kinds of main anti-multipath interference technology to the communications system performance improvement situation.
