| 摘 要： | 针对几何建模的空间相关信道复杂度较高的问题,提出了一种通用的空间相关随机MIMO信道的建模方法。构建该信道首先需产生随机独立的MIMO信道,其次将该信道进行相位补偿,最后乘上空间相关矩阵。该信道建模采用随机产生方式,同时考虑信道的时延扩展、多普勒扩展、角度扩展等多种信道参数,通过调整某些参数可生成适用于各种MIMO技术研究的信道模型,如智能天线、空间分集、复用等,并且具有计算复杂度低、产生简便的优点。

| Abstract: | A general stochastic spatial multiple input multiple output(MIMO)channel model is proposed in this paper. The stochastic spatial MIMO channel modeling method contains three steps, first step is to generate the random independent MIMO channel, the second step is to compensate the signal phase shift, and the last step is to multiply spatial correlated matrices. The modeling method produces the stochastic fading involving delay spread, doppler spread, angle spread, etc. to generate a general MIMO channel complying with various MIMO techniques such as smart antenna, spatial diversity and spatial multiplexing by adjusting certain parameters. The proposed model has the advantage of low computing complexity and can be conveniently generated. |
