Sub-array based hybrid precoding design for downlink millimeter-wave multi-user massive MIMO systems
Abstract: In this paper, we investigate the downlink of millimeter-wave multi-user massive MIMO systems, and propose a hybrid precoding scheme based on a sub-array architecture to achieve a better ...
Abstract: In line-of-sight scenarios multi-user orbital angular momentum (MU-OAM) wireless backhaul systems require accurate alignment of the transceiver beams to ensure the system performance.
