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.
Under the premise of considering the correlation between orthogonally polarized subchannels, it is pointed out that the traditional analysis model can not reflect the influence of polarization direction on the correlation and proposes a new modeling theory to modify and supplement the traditional model. Then it points out that the traditional It is an inaccurate approximation method to calculate the correlation coefficient in the case of hybrid diversity by using the correlation coefficient of the antenna in the case of distance diversity and polarization diversity in the model. It is proposed that the direct use of the statistical data when the antenna is under mixed diversity is modeled, This new model can accurately reproduce the correlation coefficients between subchannels to meet the needs of high precision.
