Antenna subset selection in combination with dualpolarized antennas offers a better solution for compact and lowcomplexity devices using higher order Multiple-Input Multiple-Output (MIMO). In this paper we provide another degree of freedom to the existing dual-polarized MIMO and analyze the performance of antenna selection for triple-polarized MIMO systems with maximum ratio combining receivers. We theoretically
analyze the impact of cross-polar discrimination on the achieved antenna selection gain for both dual and triplepolarized MIMO for non line of sight channels. We proceed to derive the outage probabilities and observe that these systems achieve significant performance gains for compact configurations with only a nominal increase in complexity. We observe that at higher cross polarization discrimination and lower transmit signal to noise ratio, the outage performance for a dual-polarized system is almost the same as triple-polarized system with joint transmit/receive antenna selection. With selection at only one end of the link, the triple-polarized system performs better than dual-polarized counterpart at higher values of transmit SNRs.We also found out that the available degrees of freedom significantly increase with lower values of cross polarization discrimination.
