This paper presents a simple model for polarized multiple-input multiple-output (MIMO) channels. At first, the model is desired for line-of-sight (LOS) scenario, and then generalized for non-LOS (NLOS) case. The analysis of the crosspolarization discrimination (XPD) for a 2x2 MIMO systems shows that the XPD depends on both the antenna patterns and the polarization mismatch between the transmit and receive antenna pairs. In addition, this theoretical model can be easily integrated into the spatial channel model (SCM) to predict the dual-polarized MIMO channels for LOS and non-LOS (NLOS) scenarios. The comparisons between simulation results and measurements further proof this model's applicability.
