摘　　要：CPMA专利技术是一项专为宽带卫星系统的返回链路设计的多址技术 ,本文介绍了 CPMA技术的基本思想 ,同时在系统同步的前提下对 CPMA技术的调制解调过程及用户容量进行了理论分析和计算机仿真 。CPMA was a patent technique about the downlink of broad-band satellite communication system. In this paper, the basic theory of CPMA technique was introduced. Then, the academic analysis of its modulation/demodulation process and user capability under system synchronization situation was carried out. Finally, the BER curves for multiuser were obtained by computer simulation.
