卫星移动通信Suzuki-Corazza混合信道模型仿真研究

Simulation study of Suzuki-Corazza hybrid mode in the mobile satellite channel

结合Suzuki和Corazza模型,提出了一种新的Suzuki-Corazza混合模型.深入研究了阴影衰落信道模型,直射路径分量和多径散射分量分别受2个相互独立的Lognormal分布随机过程的影响.给出了混合模型的仿真实现框图、功率谱密度函数、自相关函数、概率密度函数(PDF)的详细推导过程、概率密度函数和累积分布函数(CDF)的理论仿真比较图.仿真结果与分析结果吻合得非常好.

This research proposes a new hybrid Suzuki - Corazza model based on an integration of the Corazza mod- el and the Suzuki model, in which two independent Lognormal random processes are under the influence of the LOS signal and the multi - path signals, respectively. It gives a model of simulation diagram based on coloured Gaussian random processes, and the derivation process of power spectral density function, the autocorrelation function, prob- ability density function （PDF） and the cumulative distribution function （CDF） in detail, as well as the figures of the comparison between the theory and the simulation of the probability density function and cumulative distribution function. There is a good consistence between the simulation and the analytical results.
