摘　　要：短波通信是当今国际常用的通信手段之一,但是容受复杂电磁环境的影响。基于此,本文介绍了短波通信的原理与常见的几种干扰,详细分析了常见的干扰抑制措施,然后针对同频道内的干扰问题,分析了不同合并方式对信号性能的影响机制,并提出了基于RAKE技术的时频调制抗干扰方法,以期为相关研究提供借鉴。Short wave communication is one of the common communication means in the world, but it is affected by complex electromagnetic environment. Based on this, this paper introduces the principle of short wave communication and several common interferences, analyzes the common interference suppression measures in detail, then analyzes the influence mechanism of different combination methods on signal performance for the interference problem in the same channel, and puts forward the time-frequency modulation anti-interference method based on rake technology, in order to provide reference for relevant research.
