Multi-IRS-assisted Multi-Cell Uplink MIMO Communications under Imperfect CSI: A Deep Reinforcement Learning Approach
Junghoon Kim, Seyyedali Hosseinalipour, Taejoon Kim +2
Applications of intelligent reflecting surfaces (IRSs) in wireless networks have attracted significant attention recently. Most of the relevant literature is focused on the single…
Wireless Power Transfer with Distributed Antennas: System Design, Prototype, and Experiments
Shanpu Shen, Junghoon Kim, Chaoyun Song +1
In this paper, we design and experiment a far-field wireless power transfer (WPT) architecture based on distributed antennas, so-called WPT DAS, that dynamically selects transmit a…
Range Expansion for Wireless Power Transfer using Joint Beamforming and Waveform Architecture: An Experimental Study in Indoor Environment
Junghoon Kim, Bruno Clerckx
Far-field Wireless Power Transfer (WPT) has emerged as a potential power source for the Internet of Things (IoT) and Wireless Sensor Network (WSN).The expansion of the power transf…
Minimum Overhead Beamforming and Resource Allocation in D2D Edge Networks
Junghoon Kim, Taejoon Kim, Morteza Hashemi +2
Device-to-device (D2D) communications is expected to be a critical enabler of distributed computing in edge networks at scale. A key challenge in providing this capability is the r…
Joint Optimization of Signal Design and Resource Allocation in Wireless D2D Edge Computing
Junghoon Kim, Taejoon Kim, Morteza Hashemi +2
In this paper, we study the distributed computational capabilities of device-to-device (D2D) networks. A key characteristic of D2D networks is that their topologies are reconfigura…
