摘要
本文介绍共用天线、前端、干线传输系统的设计方案．针对系统中可能出现的信号干扰进行了分析、处理，并参照ＧＢ３１７４－８２对系统各部分的输入输出电平提出了明确的设计与计算方法．
This paper expounds the design of block antenna, front-end and trunk cable transmission system. It's analysed and solved the possible signal interference in the system, andmoreover, proposed the design and calculation of input and output electric level concerningeach part of the system with reference to the national standard (GB3174-82).
