| 摘 要： | 从多径衰落、阴影效应和多普勒效应三个方面研究宽带移动卫星通信信道的频率色散特性和多普勒功率谱非对称特性。基于WSSUS模型提出宽带移动卫星通信信道的统计模型。采用蒙特卡洛仿真方法对农村地区和城市地区两种信道的冲激响应和误码率特性进行仿真。仿真结果表明该信道模型能够真实反映宽带移动卫星通信信道的特性，对卫星通信系统关键技术设计具有参考价值。

| Abstract: | In the paper, the fading characteristics of the frequency-dispersion and dissymmetry of Doppler frequency shifts of the wideband satellite mobile communications are studied. The model for wideband satellite mobile communications channels is proposed considering the multi-path and Doppler frequency shifts. Finally, two channels of country and urban area are simulated using Monte Carlo method. The model provides a theoretic suggestion for design of the wideband satellite mobile communications systems. |
