摘要：研究了MIMO巷道几何建模技术。依据电磁波在矿井巷道环境中的特点且选用收发端水平角度功率谱作为拉普拉斯分布函数功率谱,仿真了巷道环境下MIMO天线放置角度、收发天线间距、巷道长度、莱斯因子、角度扩展和平均达到角等对空间相关函数的具体影响。仿真结果表明,巷道环境中天线放置角度对相关系数的影响较大;天线间距取较大值时,才能得到较小的相关性;相关系数还要受到天线间距和巷道长度以及角度扩展等的影响,比地面的相关性更大。
This paper stutied the MIMO roadway geometry modeling technology.On the basis of electromagnetic wave in mine roadway environment characteristics of the establishment of the MIMO channel GBDB scattering model and direct channel model,the model is derived for the correlation function,and the selection of transmitter and receiver horizontal angular power spectrum is Laplasse distribution function of power spectrum.The specific effects of tunnel environment MIMO antenna placement angle,antenna spacing,tunnel length,Les factor,angle spread and the average angle on the spatial correlation function were simulated.The simulation results show that in the environment of tunnel antennaplacement angle effect on correlation coefficient is larger,and antenna spacing for a larger value can get a lesser correlation;but correlation coefficient is also affected by the antenna spacing and tunnel length and angle expansion and so on,and the ground is correlated with greater than.
