Low-Complexity Phase-Only Polarforming for Multiuser MISO With Single-RF-Chain PRAs
This letter studies multiuser (MU) downlink polarforming with equal-amplitude, phase-only polarization-reconfigurable antennas (PRAs), each driven by a single radio-frequency (RF) chain. At each base station (BS) antenna, one polarization phase is shared by all transmitted streams, while digital precoding remains user-...
