Hybrid Beamforming for Intelligent Reflecting Surface Aided Millimeter Wave MIMO Systems

no code implementations28 May 2021 Sung Hyuck Hong, Jaeyong Park, Sung-Jin Kim, Junil Choi

As communication systems that employ millimeter wave (mmWave) frequency bands must use large antenna arrays to overcome the severe propagation loss of mmWave signals, hybrid beamforming has been considered as an integral component of mmWave communications.
