摘要
文章介绍了广播频段射频干扰的形成机理,干扰的种类以及在工作中遇到不同的干扰采取不同的补救措施。干扰,本质上是指未按频率分配规定的信号占据了合法信号的频率,造成合法信号无法正常工作。因此,对频域的分析过程,就是解决干扰问题的过程,也是广播网络优化工作的重要组成部分。解决干扰问题,不仅要对广播网络常见干扰有深刻的认识,还必须对现有广播制式的频率分配了如指掌。
This paper describes the formation of radio frequency interference mechanism, the types of interference encountered in actual engineering, and different measures againgst different interference types. Interference, in essence, refers to the signal failure caused by illegal signal occupying frequency of legal signal. Therefore, frequency domain analysis process is to resolve the interference problem, which is an important part radio network optimization. To resolve the interference problem requires a deep understanding of common interference in broadcast network,as well as good knowledge of frequency allocation of existing broadcast formats.
