Wireless-Powered Full-Duplex UAV Relay Networks Over FTR Channels

A thorough understanding of fundamental limits wireless-powered unmanned aerial vehicle (UAV) relay networks in millimeter waves is still missing. We narrow this gap by investigating the outage performance a UAV-assisted wireless network over fluctuating two-ray (FTR) channels. The FTR fading model particularly appealing since well characterizes propagation wide range frequencies, including those waves. proposed setup consists source-destination pair communicating with assistance UAV, which station operating full-duplex mode under amplify-and-forward protocol. For energy harvesting at power transfer (WPT), simultaneous information and (SWIPT), self-recycling techniques are employed together. To characterize system probability, we obtain an integral-form expression derived from approximate analysis simple closed-form asymptotic high signal-to-noise ratio (SNR) regime. Monte Carlo simulations provided to validate correctness our theoretical results provide insights on terms key parameters. Interestingly, obtained show that parameters corresponding first hop second play no role SNR. Instead, it mainly governed effect residual self-interference leading floors.
