Transformer-Based Beam Alignment for RIS-Aided mmWave Communication System
In millimeter wave (mmWave) communication systems, beam alignment is doomed to play a vital role in ensuring directional link performance. In this paper, we propose a novel transformer-based angle prediction scheme to achieve fast and effective beam alignment. Transformer is one of the hottest seq2seq models in recent times, which is utilized to build the mapping relationship between the geographic position and beam alignment angles of users in this paper. Simulation results demonstrate the performance of the proposed scheme in terms of prediction accuracy and achievable sum rate.
