摘要
在对卫星移动信道传输特性统计模型研究分类的基础上，给出了适合卫星移动信道的部分阴影扩展模型。用试验和修正的方法给出了模型参数，得到的模型适用于非静止轨道变仰角信道，分析了非静止轨道卫星通信系统窄带调制和宽带扩频调制的误码率性能，得到了有意义的结论。
Based on the statistical model classification of mobile satellite communication channel,a partial-shadowing extended model suited for mobile satellite channel is proposed. The parameters contained in the model are given by means of trial and error,the model given can be used for nongeostationary orbits channel with varying elevation angles.BER performance is analyzed for narrow-band modulation and wide-band spread spectrum modulation in nongeostationary orbits communication systems,and some useful conclusions are drawn.
