| 摘 要： | 在研究分析传统Rayleigh信道和Rice信道抽头时延模型的基础上,采用两条多径路线代替传统模型,提出一个具有确定数学表达式的简化卫星信道模型,只需对该模型中的两个参数取适当的取值,就可以得到不同的衰落强度和衰落中心频率的卫星信道.理论和仿真结果表明,当时延τ=.63ns,β=0.75时,可以获得的最大衰落幅度为10...

| Abstract: | On the basis of research and analysis of traditional Rayleigh and Rice time delay channel model,using two paths to replace the traditional channel,a simplified satellite channel model with certain expression was presented.This expression has two parameters which can decide the maximum fading amplitude and central frequency.The theory analysis and simulation results show the maximum fading amplitude is 10 dB and central frequency is 480 MHz when time delay τ=0.63 ns,β=0.75. |
