Hybrid Precoding for Massive mmWave MIMO Systems [PDF]
IEEE Access, 2019 Due to high costs and power consumptions, fully digital baseband precoding schemes are usually prohibitive in millimeter-wave massive MIMO systems. Therefore, hybrid precoding strategies become promising solutions. In this paper, we present a novel real-time yet high-performance precoding strategy.
