Hybrid Precoder Design for Angle-of-Departure Estimation with Limited-Resolution Phase Shifters
Huiping Huang, Musa Furkan Keskin, Henk Wymeersch +4
Hybrid analog-digital beamforming stands out as a key enabler for future communication systems with a massive number of antennas. In this paper, we investigate the hybrid precoder…
