Abstract
To study the effects of unmanned aerial vehicle (UAV) fuselage scattering and posture variation, a novel non-stationary geometry-based stochastic model (GBSM) is proposed for multiple-input multiple-output (MIMO) UAV channels. It consists of line-of-sight (LoS) and non-line-of-sight (NLoS) components. The factor of fuselage scattering effect (FSE) and posture are considered by introducing an FSE vector and a time-variant posture matrix into the channel model, respectively. Besides, temporal autocorrelation function (ACF) is derived and investigated in detail. Simulation results show that both FSE and posture have significant effects on the UAV channel characteristic. The agreements between theoretical and simulated results verify the correctness of the proposed model.
