在考虑正交极化子信道之间相关性的前提下，指出传统分析模型无法体现极化方向对相关性的影响，并提出一种新的建模理论对传统模型进行修改补充；然后指出传统模型中使用天线在距离分集和极化分集情况下的相关系数来计算混合分集情况下的相关系数是一种不够准确的近似方法，提出直接利用天线处于混合分集情况下的统计数据进行建模，这种新的模型可以准确复现子信道间的相关系数，满足高精度的需求.

By considering the correlations between cross-polarized sub-channels, the traditional multi-input multi-output (MIMO) channel models are proved to be unable to reflect the effect of antenna polarization on correlation coefficients. To solve the problem, a new modeling theory is proposed to amend the traditional model. Furthermore, the method of calculating correlation coefficients of the MIMO system with hybrid-diversity antennas in traditional channel models is proved to be an inaccurate approximation, and a new method of modeling with statistical data of MIMO systems with hybrid-diversity antennas is presented. The new model is able to replicate the correlation coefficients accurately and meet the high-precision requirements.-
