摘要
卫星移动通信信道是典型的衰落信道,信道的衰落会降低信号的接收质量,严重时可能导致通信中断。该文针对卫星移动通信在复杂信道条件下的衰落特性,简要介绍了分集接收抗衰落技术、自适应均衡抗衰落技术、编码抗衰落技术等方法,通过分析衰落产生的原理并结合抗衰落技术研究的现状,总结了相应的抗衰落性能。
Satellite mobile communication channel saretypical fading channel that reduce the quality of receiving signals and lead to communication interruptiononce serious.In this paper,aiming at the fading characteristicsof satellite mobile communication under complex channel conditions,diversity reception anti-fading technology is briefly introduced,adaptive equalization anti-fading technology and coding anti-fading technology are also presented.Through analyzing the principle of fading generation and combining with current research of anti-fading technology,correspondinganti-fading performancearesummarized.
