Flight Sensor Data and Beamforming based Integrated UAV Tracking with Channel Estimation using Gaussian Process Regression
Ha-Lim Song, Young-Chai Ko
With explosively increasing demands for unmanned aerial vehicle (UAV) applications, reliable link acquisition for serving UAVs is required. Considering the dynamic characteristics…
Integrating LEO Satellites and Multi-UAV Reinforcement Learning for Hybrid FSO/RF Non-Terrestrial Networks
Ju-Hyung Lee, Jihong Park, Mehdi Bennis +1
A mega-constellation of low-altitude earth orbit (LEO) satellites (SATs) and burgeoning unmanned aerial vehicles (UAVs) are promising enablers for high-speed and long-distance comm…
Robust and Low Complexity Beam Tracking with Monopulse Signal for UAV Communications
Ha-Lim Song, Young-Chai Ko
UAV communications based on an antenna array entail a beam tracking technology for reliable link acquisition. Unlike conventional cellular communication, beam tracking in UAV commu…
Integrating LEO Satellite and UAV Relaying via Reinforcement Learning for Non-Terrestrial Networks
Ju-Hyung Lee, Jihong Park, Mehdi Bennis +1
A mega-constellation of low-earth orbit (LEO) satellites has the potential to enable long-range communication with low latency. Integrating this with burgeoning unmanned aerial veh…
Throughput Maximization of Mixed FSO/RF UAV-aided Mobile Relaying with a Buffer
Ju-Hyung Lee, Ki-Hong Park, Young-Chai Ko +1
In this paper, we consider an unmanned aerial vehicle (UAV) aided mobile relaying system under a buffer constraint. We propose a new relaying protocol employing mixed free-space op…
