| 摘 要： | 在由中继卫星、地面中心站和移动用户组成的集中式移动卫星通信系统中,为了满足日益增长的移动用户通信业务量的需要,本文提出中心站到移动用户间的出站链路采同同步码分多址复用的广播信道,从而使通信系统利用率增高的方法,并且推导出计算误码率的公式。由计算机模拟,给出各种信噪比情况下,3、5和7路复用的误码率,并与单路时的误码率进行了比较。

| Abstract: | The centralized mobile satellite communication system consists of the relay satellite, the satellite ground station and mobile users. In order to meet the ever-increasing communication needs of mobile users, this paper presents a method of using the broadcasting channel of synchronous code division multiplex in the outbound link between a satellite ground station and mobile users so that the utilization efficiency of the system can be increased. Then the formulate for calculating the error probability of multiplex systems are derived. Compared with the case of single channel, the error probability in the case of 3, 5, and 7 channels in various signal-to-noise ratios are given. And computer simulation is carried out. |
