| 摘 要： | 由于多径效应的存在,MIMO无线传输系统的性能很大程度上取决于衰落信号空间相关性.研究基于统计的传输信道模型,及在此模型下MIMO多天线系统的接收性能.在理想基站天线结构下,用户终端(UT)的波达信号方位功率谱(APS)模型可应用到Kronecker MIMO信道模型中.研究在Kronecker MIMO信道模型中方位功率谱对MIMO分集和多天线系统性能的影响.数值仿真结果表明:此统计信道模型下的参数估计符合理论和经验;提出的统计信道模型及分析法扩展了以前的MIMO信道模型建模,降低了计算和分析的复杂度.

| Abstract: | Due to the presence of multipath effect , the performance of MIMO wireless transmission system largely depends on spatial fading correlation of arrival signals . This paper investigated on a statistical transmission channel model and the performance of MIMO multi‐antenna system under this model .In an ideal configuration of base station antennas , azimuth power spectrum (APS) model of the arrival signals for the user terminal(U T)could be applied to Kronecker MIMO channel model .This paper considered the impact of azimuth power spectrum in Kronecker MIMO channel model on the diversity and the performance of MIMO multi‐antenna system .Simulation results showed that parameter estimation under this statistical channel model satisfied theories and experiences ,the statistical channel model and its analytical method which this paper presented extended past modeling of MIMO channel model and reduced the computational and analytical complexity . |
