A Novel 3D MIMO GBSM for UAV Air-To-Air Communications
In the sixth generation (6G) era, the vision of integrated space-air-ground-sea communication networks stresses the importance of unmanned aerial vehicle (UAV) communications. This paper proposes a general three-dimensional (3D) multipleinput multiple-output (MIMO) geometry-based stochastic model (GBSM) for UAV air-to-...
