摘要
对移动卫星通信的三种典型信道进行了完整的理论分析。通信信号在不同的信道参数条件下,经过瑞利(Rayleingh)信道、莱斯(Rician)信道和阻挡效应下的莱斯信道(Rician/Lognormal)进行了计算机仿真,得到了仿真结果。经分析比较发现,信道参数不同,得到的误码率曲线不同。信道的性能主要取决于信道参数,各种因素的影响可以归结到这些参数的影响,理论分析和仿真实验结果一致。
In this paper, following a full analysis of three typical channel models in satellite mobile communication. The simulation of Rayleingh channel, Rician channel and Rician/Lognormal channel was made with different channel parameters. Then we find that as a total influence of different factors, bit error rate is different when parameter is different. The performance of channel depends on the channel parameters mainly. The results of theory analysis and simulation are consistent.
