2D-OPC Subarray Structure for Efficient Hybrid Beamforming over Sparse mmWave Channels
Millimeter-wave (mmWave) communication is a key technology of 5G new radio (NR) mobile communication systems. Efficient beamforming using a large antenna array is important to cope with the significant path loss experienced in the mmWave spectrum. The existing fully digital beamforming scheme requir...
