摘　　要：分析了临近空间通信信道的衰减特性,从多径衰落和降雨衰减两个方面综合考虑,建立了一种新的两状态信道统计模型,使用MATLAB进行了计算机仿真。仿真结果表明,该模型能够较好地反映临近空间通信的信道特性,对于临近空间通信的开发和研究具有重要意义。The fading characteristic of the near space communication channel is analysed, and a new two - state statistical channel model which considers multipath fading and rain attenuation is proposed. The result of MAT- LAB simulation shows that the model can reflect the fading characteristic of the near space communication channel, and is of great significance in exploration and research of near space communication.
