摘要
大容量数字无线通信系统对多径传输引起的传播恶化很敏感,所以抗多径衰落技术是数字通信中研究重要课题之一。本文分析了几种主要的抗多径衰落技术,并用Matlab仿真了这些技术对通信系统性能改善的情况,此得出一些结论。这些结论对研究不同衰落下的校正方案、设计最佳均衡器结构等有参考价值。
The high capacity digital wireless communication systems are inherently sensitive to waveform distortion caused by multipath transmission,and the correction techniques for multipath fading are always one of the important problems investigated in digital communication.This paper analyses several main correction techniques for multipath fading,and simulates their abilities to im-prove the communication performance.Some remarks are concluded.These remarks are helpful for studying the correction method under different fading channel and designing the best equalizers.
