Massive MIMO With Dual-Polarized Antennas

open access: yesIEEE Transactions on Wireless Communications, 2023
This paper considers a single-cell massive MIMO (multiple-input multiple-output) system with dual-polarized antennas at both the base station and users. We study a channel model that includes the key practical aspects that arise when utilizing dual-polarization: channel cross-polar discrimination (XPD) and cross-polar correlations (XPC) at the ...
