Wireless Information and Power Transfer for IoT: Pulse Position Modulation, Integrated Receiver, and Experimental Validation
Junghoon Kim, Bruno Clerckx
Simultaneous wireless information and power transfer (SWIPT) has emerged as a viable technique to energize and connect low-power autonomous devices and enable future Internet of Th…
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…
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…
Experimental Analysis of Harvested Energy and Throughput Trade-off in a Realistic SWIPT System
Junghoon Kim, Bruno Clerckx, Paul D. Mitcheson
We build a realistic Simultaneous Wireless Information and Power Transfer (SWIPT) prototype and experimentally analyse the harvested energy and throughput trade-off. Both time-swit…
