Repeater-Assisted Massive MIMO Downlink Performance with Calibration Errors
Kohei Ueda, Anubhab Chowdhury, Koji Ishibashi +1
Reciprocity-based downlink beamforming is imperative for a scalable time-division duplex massive multiple-input multiple-output~(MIMO) deployment. Specifically, for a dual-antenna…
