Wireless Powered UAV Relay Communications over the Fisher-Snedecoer ƒ Fading Channels

In this paper, we investigate the performance of unmanned aerial vehicle (UAV) relaying systems with simultaneous wireless information and power transfer over the recently proposed Fisher-Snedecoer composite F fading channels. Closed form exact expressions for the outage probability (OP) and the average capacity (AC) of both decode-and-forward (DF) and amplify-and-forward (AF) protocols are derived. In the high signal-to-noise ratio region, we obtain asymptotic OP expressions to provide valuable insights into the impact of system and fading parameters on the UAV relaying performance. Finally, the accuracy of our derived expressions is validated via Monte Carlo simulations.
