Combating Beam Misalignment in mmWave UAV Networks: An Attitude Compensation-Based Method

The attitude change of unmanned aerial vehicles (UAVs) caused by wind fields may lead to beam misalignment problems in millimeter wave (mmWave) UAV networks, which would reduce the transmission spectral efficiency (SE) significantly. In this paper, we propose a novel attitude compensation-based beam...

Summary:The attitude change of unmanned aerial vehicles (UAVs) caused by wind fields may lead to beam misalignment problems in millimeter wave (mmWave) UAV networks, which would reduce the transmission spectral efficiency (SE) significantly. In this paper, we propose a novel attitude compensation-based beam tracking (ACBT) method, which enables UAVs to maintain beam alignment despite attitude changes. Simulation results demonstrate that, by adjusting the beam direction dynamically, the proposed ACBT method can maintain the stability and efficiency of mmWave links in UAV networks, thus enhancing the overall performance of aerial communications.
