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

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.

Design of Slepian-Wolf codes by channel code partitioning
, 2004 A Slepian-Wolf coding scheme that can achieve arbitrary rate allocation among two encoders was outlined in the work of Pradhan and Ramchandran. Inspired by this work, we start with a detailed solution for general (asymmetric or symmetric) Slepian-Wolf ...

A Doping Bits Based BP Decoding for Rateless Distributed Source Coding Applications
Journal of Electrical and Computer Engineering, Volume 2014, Issue 1, 2014., 2014 A novel doping bits based belief propagation decoding algorithm, for rate‐adaptive LDPC codes based on fixed bipartite graph code, is proposed. The proposed work modifies the decoding algorithm, by converting the puncturing nodes to regular source nodes and by following the encoding rule at the decoder. The transmitted doping bits in place of punctured

Distributed Joint Source-Channel Coding-Based Adaptive Dynamic Network Coding
IEEE Access, 2020 Distributed Source Coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. More specifically, Distributed Joint Source-Channel coding (DJSC) is associated with the scenario, where ...

Multiple Description Coding with Side Information: Practical Scheme and Iterative Decoding
EURASIP Journal on Advances in Signal Processing, 2009 Multiple description coding (MDC) with side information (SI) at the receiver is particularly relevant for robust transmission in sensor networks where correlated data is being transmitted to a common receiver, as well as for robust video compression. The

Low‐Complexity Compression Algorithm for Hyperspectral Images Based on Distributed Source Coding
Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 A low‐complexity compression algorithm for hyperspectral images based on distributed source coding (DSC) is proposed in this paper. The proposed distributed compression algorithm can realize both lossless and lossy compression, which is implemented by performing scalar quantization strategy on the original hyperspectral images followed by distributed ...
