| 摘 要： | 在数字微波传输系统的建设中，受地理条件的限制，架设天馈系统往往十分困难。如果利用已有模拟微波传输通道，实现模拟和数字微波信号的混合传输，不仅可以节约资金，又能达到信号数字化传输的目的。以湖北卫视上星微波数字化改造项目这一实际案例，着重介绍了模拟和数字微波信号共用天馈系统进行混合传输及需要注意的几个问题。

| Abstract: | Antenna-Feeder system is difficult to set up in the construction of digital microwave transmission system because of the geographic restriction. The realization of mixed transmission of analog and digital microwave by existing analog microwave transmission path can help to save capital and achieve the aim of digital transmis- sion of signals. Taking the practical case of satellite microwave digitalization of Hubei TV Station as an example, this article presents the mixed transmission by analog and digital microwave signals sharing antenna-feeder system, and also some problems to notice. |
