Channel Model for Polarized MIMO Systems With Power Radiation Pattern Concern

Antenna polarization is an effective resource to be exploited for space-limited devices to support a large network payload. However, channel modeling with regard to antenna polarization is still in its early stages. This paper assesses several existing channel models that support antenna polarization, and the advantages and disadvantages of the existing models are clearly summarized. To maintain the advantages (e.g., supporting the MIMO array extension and considering the antenna radiation pattern) and overcome the disadvantages (e.g., reducing modeling complexity but preserving accuracy), this paper proposes a 3-D channel model for polarized MIMO (CM
_3D
-PMIMO) systems. In particular, the proposed channel model considers the power radiation pattern of polarized array systems that could be used for evaluation of an energy efficient transmission technique based on polarized MIMO systems. Similar to conventional works, the proposed CM
_3D
-PMIMO is verified via correlations between the polarized links, and the Monte Carlo simulation reliability for performance evaluation of MIMO technologies under CM
_3D
-PMIMO is also validated by packet-error-rate analysis.
