摘　　要：针对微波中继通信单跳通信距离近、后勤保障困难、机动性差及难以适应复杂地形等缺点,通过分析微波超视距信道特性,提出微波超视距传输的设计思路。基于对微波超视距链路预计公式的推导,为系统设计提供基础和保障。通过对信道类型的分析,提出针对瑞利信道的抗衰落技术措施,进行仿真和分析。最后给出了一个工程实例,理论及实践的一致性结果,证明了其应用效果。Aimed at the problems of microwave relay communication system such as the short communication distance, moredifficult malntenance,poor mobility and enviromnental adaptability, etc., this paper puts forward a design method of mierowave BLOStransmission based on analyzing channel characteristics of microwave BLOS communication. On the basis of prediction formulas deriva-tion of microwave BLOS link, a theoretical basis is provided to the design of transmission system. By analyzing the channel type, theanti-fading technology is put forward and simulated for rayleigh channel. At last,an engineering example is given,and the consistency oftheoretical analysis and practice results show that this design is available.
