摘要

We investigate in this paper the use of dual polarized antennas in Multiple Input Multiple Output (MIMO) systems[1][2]. Among the existing channel models for MIMO systems, we perform the geometric NLOS (Non Line of Sight) propagation channel model. Our analysis evaluates the gain in capacity of a MIMO system with two transmit antennas and two receive antennas when comparing the capacity of the dual polarized MIMO system to the capacity of MIMO system with single polarized antennas. The effect of the antenna depolarization as well as the spatial correlation of antennas are considered when evaluating the capacity gain.
