Multi-Way Relay Networks: Orthogonal Uplink, Source-Channel Separation and Code Design
, 2012 We consider a multi-way relay network with an orthogonal uplink and correlated sources, and we characterise reliable communication (in the usual Shannon sense) with a single-letter expression. The characterisation is obtained using a joint source-channel

On Separation for Multiple Access Channels [PDF]
, 2007 We examine the issue of separation for multiple access channels. We demonstrate that source-channel separation holds for noisy multiple access channels, when the channel operates over a common finite field.

Minimum Cost Data Aggregation for Wireless Sensor Networks Computing Functions of Sensed Data
Journal of Sensors, Volume 2015, Issue 1, 2015., 2015 We consider a problem of minimum cost (energy) data aggregation in wireless sensor networks computing certain functions of sensed data. We use in‐network aggregation such that data can be combined at the intermediate nodes en route to the sink. We consider two types of functions: firstly the summation‐type which includes sum, mean, and weighted sum ...

Neural Rate-Adaptive LDPC Decoding for the Slepian-Wolf Problem
IEEE Open Journal of Signal ProcessingDistributed source coding (DSC) enables efficient compression of correlated sources by performing independent encoding and joint decoding. Slepian-Wolf coding plays a central role in DSC, as it allows near-lossless compression of correlated data at rates

BEST FIT MODELS TEST FOR THE VIRTUAL CHANNEL IN DISTRIBUTED VIDEO CODING [PDF]
Journal of Engineering Science and Technology, 2011 Wyner-Ziv (WZ) video coding – a particular case of distributed video coding (DVC) – is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems.

Journal of Control Science and Engineering, Volume 2015, Issue 1, 2015., 2015 Energy efficiency in wireless sensor network (WSN) is one of the primary performance parameters. For improving the energy efficiency of WSN, we introduce distributed source coding (DSC) and virtual multiple‐input multiple‐output (MIMO) into wireless sensor network and then propose a new data transmission scheme called DSC‐MIMO.

TRANSFORM DOMAIN SLICE BASED DISTRIBUTED VIDEO CODING [PDF]
Journal of Engineering Science and Technology, 2011 Distributed video coding depends heavily on the virtual channel model. Due to the limitations of the side information estimation one stationary model does not properly describe the virtual channel. In this work the correlation noise is modelled per slice

Interference Channels With Arbitrarily Correlated Sources
, 2009 Communicating arbitrarily correlated sources over interference channels is considered in this paper. A sufficient condition is found for the lossless transmission of a pair of correlated sources over a discrete memoryless interference channel.

Multiband CCD Image Compression for Space Camera with Large Field of View
Journal of Applied Mathematics, Volume 2014, Issue 1, 2014., 2014 Space multiband CCD camera compression encoder requires low‐complexity, high‐robustness, and high‐performance because of its captured images information being very precious and also because it is usually working on the satellite where the resources, such as power, memory, and processing capacity, are limited.
