Robust and Low-Overhead Hybrid Beamforming Design With Imperfect Phase Shifters in Multi-User Millimeter Wave Systems
Phase shifters, often applied for analog beamforming in hybrid millimeter wave systems, are usually imperfect with random phase and gain errors brought by manufacture imperfections. Due to the uncertainty and nonreciprocity of random phase and gain errors, the digital precoder cannot eliminate the i...
