摘要
从多径效应、阴影效应、多普勒效应和电离层闪烁等方面具体分析了卫星移动通信信道传输特性,并从单状态统计模型和多状态统计模型两方面详细介绍了瑞利信道模型、莱斯信道模型、对数正态衰落信道模型、Loo模型、Corazza模型、Lutz两状态信道模型和五状态M arkov信道模型,最后对未来卫星移动通信信道模型研究做了展望。
To research the technologies and performances of the satellite mobile communications systems,it is necessary to know the physical channel characteristics.In this paper,it concretely analyzes satellite mobile communication channel propagation characteristics through multipath effects,shadowing effects,Doppler effects,ionosphere glitter and other aspects,and Rayleigh channel model,Rice channel model,lognormal channel model,Loo model,Corazza model,Lutz model,a five-state Markov model are studied from the aspects of single-state statistical model and multi-state statistical model.At last,it expects the research of future satellite mobile communication channel models.
