| Sumario: | To enhance the security of unmanned aerial vehicle (UAV) communication system with delayed channel state information (CSI), two physical layer security schemes based on 3D beamforming are propsed, namely destination-specific (DS) scheme and eavesdropper-null (EN) scheme. Through 3D beamforming, the UAV carries out beamforming design in horizontal and vertical directions, which improves the safety degree of freedom. The expressions of secrecy outage probability about two schemes are derived, and the influence of system parameters on the secrecy outage probability is studied. Simulation results verify that the 3D beamforming schemes can greatly reduce the secrecy outage probability and improve the security of UAV communication system. |
