- “In the field of near-field wideband communication, a robust deep reinforcement learning algorithm is proposed to enhance users' achievable rate by jointly optimizing active and passive beamforming. Expert introduced a delay-phase hybrid precoding structure to facilitate wideband beamforming and mitigate the biased estimation issue. Simulation results show that the proposed algorithm outperforms existing ones.”
