- In this paper, we present the study results on the possible multipath channel models for UAV(unmanned aerial vehicle) based broadcasting. In UAV based communications, the channel models consider only the path losses, the received signal strength and the conditions for Rayleigh/Ricean channel but present no multipath profiles for A2G(air-to-ground) channel, while multipath channel models in A2G channel is necessary for UAV based broadcasting to analyze reception performances. Thus according to the decision criterion of Rayleigh/Ricean channel in the UAV communication, we tried to combine approximately this criterion with DVB-T2 multipath channel models of terrestrial broadcasting. We also discussed on the preparations for the influences of yaw and tilt in UAV based broadcasting.
