Correlation Effects and Channel Capacities for MIMO Polarization Diversity
In consequence of the high demande for high transmission data rates in the outdoor and indoor environment, an exploitation of multiple-input multiple output (MIMO) systems appears recently. The MIMO channel is obviously characterized by antenna configuration and propagation environment. The antenna configuration is responsible mainly for the antenna correlation effect which can be reduced by increasing antenna array spacing or by employing multi-polarized antenna arrays. In this paper, we assume that all scatterers are uncorrelated, independent and identically distributed (i.i.d). In addition we investigate the channel capacity of single, dual and triple polarized dipole antennas compared with omni-vertical and omni-horizontal antennas with various solid angles based on 2×2 and 3×3 MIMO systems. The results of simulations illustrate that a combination of angular and polarization diversities can be exploited to increase the transmission performance.
