WLC11-6: Antenna Selection for Compact Dual-Polarized MIMO Systems with Linear Receivers

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 dualpolarized 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.

Antenna Selection in Polarization Reconfigurable MIMO (PR-MIMO) Communication Systems

“…On the other hand, polarization diversity is not taken into account in the majority of previous research works. Although there are previous reports that consider polarization diversity with antenna selection, they consider fixed antenna polarization such as dual-polarized antennas in [34] or tri-polarized antennas in [35]. In contrast, we exploit polarization reconfigurable hybrid antenna selection and MRT (PR-HS/MRT) which significantly outperforms that of the conventional scheme of the HS/MRT system.…”

Transmitter/receiver polarisation optimisation based on oblique projection filtering for mainlobe interference suppression in polarimetric multiple‐input–multiple‐output radar

“…The polarimetric MIMO radar can obtain more target scattering information since the radar possesses a polarisation diversity capability. The polarimetric MIMO array is widely applied in the wireless communication systems for improved performance [24, 25]. The distributed polarimetric MIMO radar is explored in [26–29].…”
