摘　　要：在分析Ka波段移动卫星信道的统计特性的基础上,建立了包括多径衰落、阴影遮蔽以及Ka波段所特有的雨衰影响的Ka波段移动卫星信道的综合模型,并进行了系统性能的实验仿真.同时通过理论计算,给出了该信道误码率的理论上限,并与仿真结果进行比较,证明了Ka波段移动卫星信道模型的合理性.该模型为分析系统的性能提供了一个有力的系统平台.The statistical characteristics of the mobile satellite channel at Ka-band are analysed. Weather conditions, as well as multi-path fading and shadowing are taken into account and a comprehensive simulation model is proposed. System performance simulations are conducted based on the channel and system simulation model. Meanwhile, the analytical derivation of the Ber performance at Ka-band is derived and the results are compared with the simulated results, which proves that the Ka-band mobile satellite channel is reasonable and valid. The model can function as a powerful tool for further system performance experiments.
