摘要
在矢量信道环境中提出了一种基于超短波地空通信的椭圆信道模型,推导出了地面接收信号的标准多径时延和波达方向的概率密度函数,对标准多径时延、波达方向和接收功率进行了仿真,分析了V/UHF地空通信的信道特性,表明了多径效应对超短波地空通信的影响。
An elliptical channel model for air-to-ground communication in the vector channel environment is proposed. The probability density functions of the normalized multipath delay and DOA of the received signals on the ground are derived; the normalized multipath delay, D0A and the received power are simulated; the characteristics of V/UHF air-to-ground communication channel are analyzed; and the influence of the multipath on V/UHF air-to-ground communication is shown.
