abstract = "To establish and maintain a stable communication link between unmanned aerial vehicle (UAV) and base station (BS), we propose beam training method based on DFT codebook. Especially, the proposed beam training compensates doppler shifts caused by high-speed UAV and estimates an exact angle-of-arrival (AoA). From simulation results, we show that the proposed scheme accurately estimates the exact AoA by compensating the effect of doppler shifts compared to conventional scheme."
