移动通信作为一个系统来讲,它包含着各个方面的内容。它不仅有收发信设备、天馈系统、控制管理部分,还要从电波传播特性角度出发选用频段,考虑多路复用制度(多址制度)、调制、话音编码、信令方式、纠错编码以及交换等等,所以移动通信是一个综合性强、技术复杂的系统,但又是生命力很强的系统。移动通信已受到社会各方面的青睐,军事通信当然也离不开移动通信。实际上移动通信最早是在军队中使用的。
As a system of mobile communications, it contains all aspects of content. It not only has the sending and receiving equipment, the antenna system, the control management part, but also selects the frequency band from the perspective of the radio wave propagation characteristics, considering the multiplexing system (multiple access system), modulation, voice coding, signaling, error correction coding Exchange and so on, so mobile communication is a comprehensive, technically complex system, but also a very viable system. Mobile communications has been favored by all sectors of society, of course, military communications can not be separated from mobile communications. In fact, mobile communications were first used by the military.
