Practical Distributed Reception for Wireless Body Area Networks Using Supervised Learning
Jihoon Cha, Junil Choi, David J. Love
Medical applications have driven many areas of engineering to optimize diagnostic capabilities and convenience. In the near future, wireless body area networks (WBANs) are expected…
Low-Complexity Algorithm for Outage Optimal Resource Allocation in Energy Harvesting-Based UAV Identification Networks
Jae Cheol Park, Kyu-Min Kang, Junil Choi
We study an unmanned aerial vehicle (UAV) identification network equipped with an energy harvesting (EH) technique. In the network, the UAVs harvest energy through radio frequency…
IRS-Aided Energy Efficient UAV Communication
Hyesang Cho, Junil Choi
Unmanned aerial vehicles (UAVs) have steadily gained attention to overcome the harsh propagation loss and blockage issue of millimeter-wave communication. However, UAV communicatio…
Hybrid Beamforming for Intelligent Reflecting Surface Aided Millimeter Wave MIMO Systems
Sung Hyuck Hong, Jaeyong Park, Sung-Jin Kim +1
As communication systems that employ millimeter wave (mmWave) frequency bands must use large antenna arrays to overcome the severe propagation loss of mmWave signals, hybrid beamfo…
Practical Channel Estimation and Phase Shift Design for Intelligent Reflecting Surface Empowered MIMO Systems
Sucheol Kim, Hyeongtaek Lee, Jihoon Cha +3
In this paper, channel estimation techniques and phase shift design for intelligent reflecting surface (IRS)-empowered single-user multiple-input multiple-output (SU-MIMO) systems…
Performance Analysis of Satellite Communication System Under the Shadowed-Rician Fading: A Stochastic Geometry Approach
Dong-Hyun Jung, Joon-Gyu Ryu, Woo-Jin Byun +1
In this paper, we consider downlink low Earth orbit (LEO) satellite communication systems where multiple LEO satellites are uniformly distributed over a sphere at a certain altitud…
