Modeling and Space-Time Correlation Analysis of MIMO Channel

Abstract

We set up the uplink MIMO channel model between base station (BS) and mobile station (MS). Several parameters have been considered, including the distinguishable paths, the indistinguishable paths, angular spread, antenna polarization, linear receiving antenna array and other factors. Secondly, this paper simulates the space statistical properties of MIMO antenna channel by MATLAB. Analysis results show that, antenna correlation coefficient in MIMO channel increases with the increasing average arrival angle, decrease with the increasing antenna interval and angular expansion. Besides, this paper has also added the time factor into the correlation coefficient of antenna, and draw its three-dimensional space-time map, this can describe the channel change trend more intuitional .
