| 摘 要： | 在对陆地移动卫星信道传播特性分析的基础上,建立阴影环境下移动卫星信道的混合模型,并采用随机数产生器实现了该信道模型的统计特性仿真。通过与实测数据的统计特性进行比较,验证了该信道模型和仿真实现方法的正确性。由于移动卫星信道是一个复杂的时变随机信道,所以,通过随机数产生器产生的统计特性具有很好的普适性。

| Abstract: | A propagation model is proposed for predicting the propagation characteristics of the Land Mobile Satellite Channels caused by shadowing.The simulation of the model is based on Random Number Generators that generate data sets to compute the fading statistics of the propagation channels.The validity of the model and simulation method is confirmed by comparing with the fading statistics from the experimentally measured data.Because the Land Mobile Satellite Channel is a complex time variant stochastic channel,the statistics characteristic generated by Random Number Generators has good practicability. |
