Then , base on the determine channel modeling methods , we present a frequency - selective mimo fading channel with von mises probability density function , which is used to characterize non - uniform angle - of - arrival caused by non - isotropic scattering . then we analyze partial cross correlation function of proposed model and proved the model theoretically 然后,通過(guò)對(duì)其它多入多出信道模型的分析和對(duì)比,并基于確定性信道建模方法,建立了一種通用的頻率選擇性多入多出衰落信道模型,借助“ vonmises ”概率密度函數(shù),以描述非均勻散射體導(dǎo)致的非均勻本地來(lái)波方向分布。
