摘要
分析了移动卫星通信信道的传输特征，建立并计算机模拟了移动卫星信道的统计模型，并在此基础上，建立了理想的Ｋ用户直接扩频码分多址（ＤＳＣＤＭＡ）收发系统，研究其下行链路的误码性能。
Based on a brief analysis of transmission characteristics of satellite mobile communication channels, this paper presents a channel model of satellite mobile communication and shows signal envelop, PDF and envelop spectrum. This paper further sets up a receiving and transmitting system of K user DS CDMA and studies the basis code error property on down link of a satellite mobile communication.
