本文研究一种能与现有专用地面移动无线电设备相兼容的数字话音技术(自适应坛量调制ADM/FSK)。文章分析的技术问题如同信道配置距离、邻道配置距离、基带滤波、和模/数同信通的兼容性等。这些都涉及到联邦通讯委员会(FCC)的规定。文章并建议修改有关的规定、以适应这种数字话音设备的要求。
This article looks at a digital voice technology (Adaptive Mun Modulation ADM / FSK) that is compatible with existing proprietary terrestrial mobile radios. Article analysis of technical issues such as the channel configuration distance, the adjacent channel configuration distance, baseband filtering, and analog / digital with the compatibility of the letter. These are all related to the Federal Communications Commission (FCC) rules. The article also proposed to amend the relevant provisions to meet the requirements of such digital voice equipment.
