Channel Capacity Performance for MIMO Polarized Diversity Systems
In recent years, geometric scattering models appear to simplify geometries and scattering characterizations. These models are based on Ray-tracing models with scattering mechanism considering single bounce or double bounce. Different statistics can be used such as uniform, Gaussian, von Mises and Laplacian distributions. In this paper, the uniform distribution is used to provide elevation and azimuth angle distribution of each scatterer in three dimensional model. Additionally, for single bounce, there is only one reflection. Each scattering process is represented by a dyad matrix corresponding to the depolarization and the distortion of the electromagnetic wave. The validation of dual-polarized MIMO channels is examined and compared with the single-polarized MIMO channels. The simulation results demonstrate that the transmit and receive antenna correlations can be reduced, so that the channel capacity can be improved for dualpolarized MIMO channels.
