A physical MIMO radio channel model for multi-element multi-polarized antenna systems

Abstract

A physical multi-input multi-output (MIMO) spatio-temporal channel model for simulation of multi-element multi-polarized antenna systems is presented. The model is based on electromagnetic (EM) scattering, hence including many of the channel characteristics encountered in practice. A compact channel expression is obtained by introducing a dyad formulation of the scattering from arbitrary objects. The polarization properties of the channel and the antennas are included in the model, thereby allowing studies of the impact of different antenna arrangements and polarizations. Simulation results are presented where channel properties such as spatial correlation, channel capacity, and time evolution are calculated for microcell and picocell scenarios.
