山西广电传输网长距离传输数字微波信号的工程实践

摘要

Shanxi radio and TV transmission network using digital microwavetransmission as a means of the ra -dio and television of route network , this paper mainly to improve the transmission efficiency and quality of the anti-fading techniques as the center , the space diversity , frequency diversity ,increased repeater technology to improve the microwave signal long distance transmission and the role of effect of our province , for the digital-trunk network microwave signal in long distance transmission and secure broadcast provides a good solution .%山西广播电视无线传输网采用数字微波作为全省广播电视干线网的传输手段，主要以提高传输效率和传输质量的各种抗衰落技术手段为中心，阐述了空间分集、频率分集、增加直放站等技术对长距离传输微波信号的作用和效果，为干线网中数字微波信号的长距离传输与安全播出提供了很好的解决办法。
