摘要
针对传统MIMO随机空间信道模型中,仰角和方位角采用独立分布,并没有准确反映信道的真实环境,充分考虑三维环境下三维角功率分布和极化天线引起的全面电磁波传播特性,仰角和方位角采用混合VMF分布,以及采用不相等的主极化率。基于以上模型,推导出信道的相关表达式,并通过2×2天线的仿真研究,分析参数对模型的影响,最后和其他文献的结果比较,证实本文模型的合理性和有效性。
According to the traditional MIMO random space channel raodel, there is no full consideration of space propagation characteristics but elevation and azimuth adapt independent distribution, this paper fully considers overall electromagnetic wave propagation characteristics caused by three-di- mensional Angle power distribution and polarization antenna in three dimensional environment, which adapts elevation and azimuth of mixed VMF distribution and not equal co-polarization rate. Based on the above model, the channel correlation expression is deduced and the influence of the parameters on the model through the 2 × 2 antenna simulation research is analyzed. Finally, it is shown that the model given is reasonable and effective through comparison with other literature.
