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…
On Secure Source Coding with Side Information at the Encoder
Yeow-Khiang Chia, Kittipong Kittichokechai
We consider a secure source coding problem with side information (S.I.) at the decoder and the eavesdropper. The encoder has a source that it wishes to describe with limited distor…
Energy Cooperation in Cellular Networks with Renewable Powered Base Stations
Yeow-Khiang Chia, Sumei Sun, Rui Zhang
In this paper, we propose a model for energy cooperation between cellular base stations (BSs) with individual hybrid power supplies (including both the conventional grid and renewa…
Compression with Actions
Lei Zhao, Yeow-Khiang Chia, Tsachy Weissman
We consider the setting where actions can be used to modify a state sequence before compression. The minimum rate needed to losslessly describe the optimal modified sequence is cha…
Estimation with a helper who knows the interference
Yeow-Khiang Chia, Rajiv Soundararajan, Tsachy Weissman
We consider the problem of estimating a signal corrupted by independent interference with the assistance of a cost-constrained helper who knows the interference causally or noncaus…
Multi-Terminal Source Coding With Action Dependent Side Information
Yeow-Khiang Chia, Himanshu Asnani, Tsachy Weissman
We consider multi-terminal source coding with a single encoder and multiple decoders where either the encoder or the decoders can take cost constrained actions which affect the qua…
Cascade, Triangular and Two Way Source Coding with degraded side information at the second user
Yeow Khiang Chia, Haim Permuter, Tsachy Weissman
We consider the Cascade and Triangular rate-distortion problems where the same side information is available at the source node and User 1, and the side information available at Us…
An Achievability Scheme for the Compound Channel with State Noncausally Available at the Encoder
Chandra Nair, Abbas El Gamal, Yeow-Khiang Chia
A new achievability scheme for the compound channel with discrete memoryless (DM) state noncausally available at the encoder is established. Achievability is proved using superposi…
Wiretap Channel with Causal State Information
Yeow-Khiang Chia, Abbas El Gamal
A lower bound on the secrecy capacity of the wiretap channel with state information available causally at both the encoder and decoder is established. The lower bound is shown to b…
3-Receiver Broadcast Channels with Common and Confidential Messages
Yeow-Khiang Chia, Abbas El Gamal
This paper establishes inner bounds on the secrecy capacity regions for the general 3-receiver broadcast channel with one common and one confidential message sets. We consider two…
