前言我们知道,移动通信的基站的连接方式是将语音或图像视频信号经载波调制后通过发射塔传输,每座发射塔都有自己的覆盖范围,载波信号(微波)在空中从一个发射塔传向邻近的另一个或几个发射塔,塔台的信号覆盖范围在理想情况下是一个圆形区域,其分布必须满足覆盖范围相交,而手机接受信号后先将信号解调,然后得到语音及图像讯息。通常基站要保持一定的距离和密度才
Preface We know that the base station of mobile communications connection is the voice or video signals through the carrier after the carrier modulated by the transmission tower transmission, each tower has its own coverage, carrier signal (microwave) in the air from a tower transmission To adjacent one or several towers, the signal coverage of the tower is ideally a circular area whose distribution must meet the coverage intersection, and the handset receives the signal and then demodulates the signal, and then get the voice and image message. Usually base station to maintain a certain distance and density before
