Wireless Energy Beamforming using Received Signal Strength Indicator Feedback
Samith Abeywickrama, Tharaka Samarasinghe, Chin Keong Ho +1
Multiple antenna techniques that allow energy beamforming have been looked upon as a possible candidate for increasing the transfer efficiency between the energy transmitter (ET) a…
Power and Channel Allocation for Non-orthogonal Multiple Access in 5G Systems: Tractability and Computation
Lei Lei, Di Yuan, Chin Keong Ho +1
Network capacity calls for significant increase for 5G cellular systems. A promising multi-user access scheme, non-orthogonal multiple access (NOMA) with successive interference ca…
Optimal Cell Clustering and Activation for Energy Saving in Load-Coupled Wireless Networks
Lei Lei, Di Yuan, Chin Keong Ho +1
Optimizing activation and deactivation of base station transmissions provides an instrument for improving energy efficiency in cellular networks. In this paper, we study optimal ce…
Multi-Antenna Wireless Energy Transfer for Backscatter Communication Systems
Gang Yang, Chin Keong Ho, Yong Liang Guan
We study RF-enabled wireless energy transfer (WET) via energy beamforming, from a multi-antenna energy transmitter (ET) to multiple energy receivers (ERs) in a backscatter communic…
The Single-Uniprior Index-Coding Problem: The Single-Sender Case and The Multi-Sender Extension
Lawrence Ong, Chin Keong Ho, Fabian Lim
Index coding studies multiterminal source-coding problems where a set of receivers are required to decode multiple (possibly different) messages from a common broadcast, and they e…
Wireless Power Meets Energy Harvesting: A Joint Energy Allocation Approach in OFDM-based System
Xun Zhou, Chin Keong Ho, Rui Zhang
This paper investigates an orthogonal frequency division multiplexing (OFDM)-based wireless powered communication system, where one user harvests energy from an energy access point…
