A Multi-Uav Irregular-Shaped GBSM for Science and Technology Park Scenario

In this paper, the propagation properties of multiple-unmanned aerial vehicle (multi-UAV) cooperative communication channels in science and technology park scenario are investigated. A new channel impulse response (CIR) dataset is constructed by Wireless InSite through ray tracing. In-Depth analysis of the key channel statistical properties, e.g., Doppler power spectral density (DPSD), cooperative time stationarity interval and singular value spread (SVS), is conducted. A novel multi-UAV cooperative communication channels model is proposed, based on birth-death (BD) process. The accuracy of the proposed channel model is verified by the close match between ray-tracing-based results and simulation results.
