Mobile Data Offloading through A Third-Party WiFi Access Point: An Operator's Perspective
Xin Kang, Yeow-Khiang Chia, Sumei Sun +1
WiFi offloading is regarded as one of the most promising techniques to deal with the explosive data increase in cellular networks due to its high data transmission rate and low req…
Cost minimization for fading channels with energy harvesting and conventional energy
Xin Kang, Yeow-Khiang Chia, Chin Keong Ho +1
In this paper, we investigate resource allocation strategies for a point-to-point wireless communications system with hybrid energy sources consisting of an energy harvester and a…
Ergodic Sum-Rate Maximization for Fading Cognitive Multiple Access Channels without Successive Interference Cancellation
Xin Kang, Hon Fah Chong, Yeow-Khiang Chia +1
In this paper, the ergodic sum-rate of a fading cognitive multiple access channel (C-MAC) is studied, where a secondary network (SN) with multiple secondary users (SUs) transmittin…
Energy-Efficient, Large-scale Distributed-Antenna System (L-DAS) for Multiple Users
Jingon Joung, Yeow Khiang Chia, Sumei Sun
Large-scale distributed-antenna system (L-DAS) with very large number of distributed antennas, possibly up to a few hundred antennas, is considered. A few major issues of the L-DAS…
A Note on Broadcast Channels with Stale State Information at the Transmitter
Hyeji Kim, Yeow-Khiang Chia, Abbas El Gamal
This paper shows that the Maddah-Ali--Tse (MAT) scheme which establishes the symmetric capacity of two example broadcast channels with strictly causal state information at the tran…
Secure Source Coding with a Public Helper
Kittipong Kittichokechai, Yeow-Khiang Chia, Tobias J. Oechtering +2
We consider secure multi-terminal source coding problems in the presence of a public helper. Two main scenarios are studied: 1) source coding with a helper where the coded side inf…
