远距离大容量微波通信链路可靠工作非常困难。针对此问题，在传统微波接力通信传输链路设计方法的基础上，分析了大容量远距离微波链路难点和多种主要抗多径干扰技术的特点，提出微波链路抗多径衰落和微波设备抗多径衰落根据信道特点联合设计才能保证通信系统可靠工作，并给出了一个信息传输速率155．520Mb／s、传输距离121km的微波链路设计验证实例，为大容量远距离微波中继系统的工程设计提供了一种借鉴方式。

It is difficult for large capacity long distance microwave relay communication link to work reliably. Based on the tradi- tional method for microwave relay communication link design, the characteristics of large capacity long distance microwave link and va- rious anti-muhipath interference technologies are analyzed, an idea of microwave relay link and microwave radio anti-multipath fading design to cancel interference is proposed, and then a design example of microwave relay link with an information transmission rate of 155. 520Mb/s and a transmission distance of 121km is provided, it can actively give a help for designing large capacity long distance microwave relay communication system.
