Design And Analysis of MMSE Precoder For Dual-Polarized Cell-Free Massive MIMO Systems

We consider the downlink of a cell-free (CF) massive multiple-input-multiple-output (mMIMO) system, where each access point (AP) has multiple dual-polarized antennas, while a user equipment has a single dual-polarized antenna. The APs use minimum mean squared error (MMSE) precoder to precode the tra...
