On wireless communication systems, Multiple-Input Multiple-Output (MIMO) systems have dramatically the potential to improve the reliability and the performance. However, the MIMO wireless channel performance is generally affected by the antenna array configuration and environment characteristic. This paper highlights the impact of angle spread and depolarization effects on the MIMO channel capacity with a focus on 4?4 uniform linear multi-polarized antenna array. The authors employ a geometric scattering model based on a three-dimensional double bouncing model that takes into account the antenna configurations. They investigate the use of multi-polarization configurations that can provide capacity improvement over conventional single-polarization configurations.
