Robust Beam Codebooks for mmWave/THz Systems: Toward a Stochastic RL Approach

Anouar Nechi, Rainer Buchty, Mladen Berekovic +1

Millimeter-wave (mmWave) and terahertz (THz) massive MIMO systems often rely on predefined beamforming codebooks, which are usually suboptimal in Non-Line-of-Sight (NLoS) condition…
