卫星通信终端话音接入车通的分析

根据车辆运动中对卫星话音通信的应用需求,针对车辆运动噪音对卫星通信话音效果影响大,以及卫星通信话音不能供多个乘员共享使用的缺点,对卫星通信终端的话音和车通的种类、特点进行了分析;提出了通过话音接入装置将卫星通信终端二线和四线模拟话音接入到各种车通的方法,以及通过必要的协议转换将IP话音接入到数字车通的方法,可以为实际的工程应用提供参考。

Analysis on Voice Access from Satellite Communication Terminals to Vehicular Communication System

Aiming at application requirements of satellite voice communication on moving vehicles, great influence of vehicle movement on satellite communication voice effect and the disadvantage that the voice can not be shared by multi-members,this paper analyzes the voice of satellite communication terminals and the category and characteristics of vehicular communication system, and provides two methods, one is to access two-line and four-line analog voice to different vehicular communication systems, the other is to access IP voice to digital vehicular communication system,so as to provide references to practical engineering application.
