Dimension-Deficient Channel Estimation of Hybrid Beamforming Based on Compressive Sensing

Due to high hardware costs for digital beamforming, hybrid beamforming (HBF) is widely employed in millimeter-wave (mmWave) communications systems. However, the number of radio frequency chains in the analog part of HBF is far less than that of antennas, which causes a serious dimension-deficient pr...
