摘要 给出了确定晴空和降雨环境中信道矩阵元素的方法.基于一种中轨卫星地-空链路多输入多输出通信系统,以西安地区实测降雨数据为依据,模拟、计算了传输分集多输入多输出通信系统、空分复用多输入多输出通信系统及单输入单输出通信系统在晴空和降雨环境中的误码率特性,分析了传输分集多输入多输出通信系统和空分复用多输入多输出通信系统在不同天气传输环境下的误码率性能,讨论了传输环境对毫米波段地-空链路多输入多输出通信系统误码率性能的影响,分析了多输入多输出通信技术对开发应用毫米波技术的重要意义. The methods to decide the elements of a channel matrix in clear and rain environments are given.The BER performances of transmitting diversity and spatial multiplexing modes are calculated and simulated based on a supposed earth-space MIMO communication system and the measured rain rate data.The BER performances of transmitting diversity and spatial multiplexing modes in different propagation environments are analyzed according to the simulated results.And the effects deduced by different propagation environments on earth-space MIMO communication are discussed.It can be concluded that MIMO technology is significant for developing earth-space communication systems at the millimeter wave band.The results given in this paper are important and valuable for exploiting the earth-space MIMO communication system at the millimeter wave band.
