| 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.

| Abstract: | 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. |
