Abstract
This paper addresses eavesdropping threats in UAVassisted millimeter-wave systems and proposes a secure communication framework using directional modulation (DM) for UAV-based base stations (UAV-BS) serving multiple ground users. To optimize the UAV's 3D deployment and multi-user DM beamforming, we formulate a max-min secure rate problem. Due to its complexity, we propose a two-stage decoupled optimization approach: first, a global search determines a near-optimal UAV deployment, and second, the DM beamforming vectors are designed using an Artificial Bee Colony (ABC) algorithm. Simulation results show that the proposed scheme significantly enhances security by ensuring clear reception for legitimate users while distorting the signal for eavesdroppers.
