Wireless Compressive Sensing for Energy Harvesting Sensor Nodes
Gang Yang, Vincent Y. F. Tan, Chin Keong Ho +2
We consider the scenario in which multiple sensors send spatially correlated data to a fusion center (FC) via independent Rayleigh-fading channels with additive noise. Assuming tha…
Carrier Frequency Offset Estimation for Two-Way Relaying: Optimal Preamble and Estimator Design
Chin Keong Ho, Patrick Ho Wang Fung, Sumei Sun
We consider the problem of carrier frequency offset (CFO) estimation for a two-way relaying system based on the amplify-and-forward (AF) protocol. Our contributions are in designin…
Energy-Efficient Relaying over Multiple Slots with Causal CSI
Chin Keong Ho, Peng Hui Tan, Sumei Sun
In many communication scenarios, such as in cellular systems, the energy cost is substantial and should be conserved, yet there is a growing need to support many real-time applicat…
Wireless Information and Power Transfer: Architecture Design and Rate-Energy Tradeoff
Xun Zhou, Rui Zhang, Chin Keong Ho
Simultaneous information and power transfer over the wireless channels potentially offers great convenience to mobile users. Yet practical receiver designs impose technical constra…
Optimal Index Codes for a Class of Multicast Networks with Receiver Side Information
Lawrence Ong, Chin Keong Ho
This paper studies a special class of multicast index coding problems where a sender transmits messages to multiple receivers, each with some side information. Here, each receiver…
