应用 随着调频多工广播通信技术的不断发展,新的独立边带-调频(ISB-FM)制式已经应用在广播、通信系统中,初步显示出节省频率资源、有利于发展辅助通信业务的优越性。 现列举几个独立边带-调频(ISB-FM)多工系统的具体应用实例。 1.信道公用通信系统 这是独立边带-调频多工制式应用在调频通信中的一个例子。系统由信道公用通信编码器和信道公用通信解码器等组成,主要应用在现有的特高频和甚高频调频通信干线上。它充分利用现有的基地台和天线等设备,只需增加信道公用编解码器,就可以实现在一个调频信
Applications With the continuous development of FM multiplex broadcast communication technology, the new ISB-FM standard has been applied in broadcasting and communication systems to initially show the advantages of saving frequency resources and facilitating the development of auxiliary communication services Sex. Here are some examples of specific applications of ISB-FM multiplexed systems. 1. Channel Public Communication System This is an example of an independent sideband-FM multiplexed application in FM communications. The system consists of a channel common communication encoder and a common channel communication decoder, which are mainly used in existing UHF and VHF frequency communication trunks. It makes full use of existing base stations and antennas and other equipment, just add channel common codec, you can achieve a FM
