摘　　要：仿真了卫星移动信道中的几种常见的统计模型,并将理论结果同仿真结果进行了比较,显示出较好的吻合性,同时基于这几种统计模型的机理,给出了Markov的两状态模型,证明了阴影过程可建模为Markov的两状态模型。Several statistical models of mobile satellite channels were simulated. Through comparison, it is proved that the simulation results conform to theoretical results. Meanwhile, the Markov models with two states are proposed based on the mechanism of these statistical models, and it demonstrates that the shadowing process can be modeled as a Markov model with 2-state.
