摘　　要：对于第三代无线通信系统来说空时接收机是重要的,为了系统仿真的需要,该文提出了一种统计空时信道模型,给出了空时信道的时间空间频率相关矩阵,合理地表征了无线移动通信信道的空间和时间特性,推导了阵列天线两单元的相关性与功率角度谱的函数关系。Space-time reveivers for the third-generation mobile communication systems is important. For a realistic simulation of such systems, a simple statistical space-time vector channel model is proposed, and the space-time-frequency correlation matrix of space-time channel which characterizes reasonably the space- and time-variant effects of the mobile radio channel is presented , and deriver the correlation between two antenna elements as a function of the power azimuth spectrum.
