摘要
卫星通信具有通信距离远、覆盖范围广、线路容量大、便于实现多址连接、组网快、机动性好等优点,已成为目前我国广播电视信号的主要传输方式之一。但由于其开放式的无线传输系统特性,不可避免地存在各种可预期或不可预期的干扰,严重影响信号传输质量及安全播出。文章详细地分析了卫星传输系统中的各种干扰因素、产生原理,并提出了针对性的应对策略,以期达到和同行交流的目的。
Satellite communication has the communication distance, wide coverage, large line capacity, easy to realize multiple access connection as well as good, fast networking and mobility, has become the current our country one of the main transmission mode of radio and television signal. But as a result of its open wireless transmission system features, inevitably there are all kinds of interference can be expected or unexpected, seriously affect the quality of signal transmission and security. This article in detail analyzes the satellite transmission system of various interference factors, principle, and puts forward the corresponding strategies to cope with the situation, in order to achieve the purpose of and peer exchange.
