Data Offloading in Load Coupled Networks: A Utility Maximization Framework
Chin Keong Ho, Di Yuan, Sumei Sun
We provide a general framework for the problem of data offloading in a heterogeneous wireless network, where some demand of cellular users is served by a complementary network. The…
Dynamic Resource Allocation for Multiple-Antenna Wireless Power Transfer
Gang Yang, Chin Keong Ho, Yong Liang Guan
We consider a point-to-point multiple-input-single-output (MISO) system where a receiver harvests energy from a wireless power transmitter to power itself for various applications.…
Wireless Information and Power Transfer in Multiuser OFDM Systems
Xun Zhou, Rui Zhang, Chin Keong Ho
In this paper, we study the optimal design for simultaneous wireless information and power transfer (SWIPT) in downlink multiuser orthogonal frequency division multiplexing (OFDM)…
The Multi-Sender Multicast Index Coding
Lawrence Ong, Fabian Lim, Chin Keong Ho
We focus on the following instance of an index coding problem, where a set of receivers are required to decode multiple messages, whilst each knows one of the messages a priori. In…
Spectral Efficiency and Energy Efficiency of OFDM Systems: Impact of Power Amplifiers and Countermeasures
Jingon Joung, Chin Keong Ho, Sumei Sun
In wireless communication systems, the nonlinear effect and inefficiency of power amplifier (PA) have posed practical challenges for system designs to achieve high spectral efficie…
