The paper introduces and analyzes polarization reconfigurable MIMO (PR-MIMO) systems, where both the transmitter and receiver can dynamically adjust the polarization of their antenna elements. It proposes two key techniques to enhance the performance of PR-MIMO systems:
Joint polarization pre-post coding: The paper derives closed-form approximations for the optimal transmit and receive polarization vectors that maximize the channel capacity bounds. It also proposes an iterative joint polarization pre-post coding scheme to jointly optimize the polarization vectors at both ends.
Polarization reconfigurable hybrid antenna selection (PR-HS-MIMO): The paper introduces two novel schemes, element-wise and global polarization reconfiguration, that combine polarization reconfigurable antennas with hybrid antenna selection. These schemes can achieve remarkable improvements in channel capacity compared to conventional HS-MIMO systems.
The paper also provides a statistical analysis of the effect of polarization reconfigurable antennas on the distribution of channel gain. Comprehensive simulation results demonstrate significant SNR and capacity gains from the proposed PR-MIMO and PR-HS-MIMO schemes.
