IMPACT OF DEPOLARIZATION EFFECTS ON MIMO POLARIZED WIRELESS CONFIGURATION
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 multipolarized antenna array. We employ a geometric scattering model based on a three-dimensional double bouncing model that takes into account the antenna configurations. We investigate the use of multipolarization configurations that can provide capacity improvement over conventional single-polarization configurations. The single-polarization configuration is dependent on the depolarization phenomena. It is found that when low depolarization and spatial correlation effects, the capacity of single-polarization configuration behaves better than that of multipolarization configuration.
