Abstract :
Antenna selection combined with dual-polarized antennas offers an attractive alternative for realizing higher order multiple-input multiple-output (MIMO) configurations in compact, low-complexity devices. In this paper we analyze the performance of antenna selection for narrowband dual- polarized MIMO channels with linear minimum mean square error (MMSE) receiver processing. We analytically study the impact of cross-polar discrimination (XPD) on the achieved selection gain. We use channel measurement data, collected at 2.4 GHz in a typical office environment, to compare the performance of spatial and dual-polarized MIMO channels with respect to antenna selection. Our bit-error-rate (BER) results indicate that antenna selection with dual-polarized antennas can achieve significant performance gains for compact configurations.
