Distributed Remote Vector Gaussian Source Coding for Wireless Acoustic Sensor Networks [PDF]

open access: yes, 2014
In this paper, we consider the problem of remote vector Gaussian source coding for a wireless acoustic sensor network. Each node receives messages from multiple nodes in the network and decodes these messages using its own measurement of the sound field ...

Identification of Sparse Audio Tampering Using Distributed Source Coding and Compressive Sensing Techniques

open access: yesEURASIP Journal on Image and Video Processing, 2009
In the past few years, a large amount of techniques have been proposed to identify whether a multimedia content has been illegally tampered or not. Nevertheless, very few efforts have been devoted to identifying which kind of attack has been carried out,

Distributed Joint Source-Channel Coding Using Quasi-Uniform Systematic Polar Codes

open access: yesEntropy, 2018
This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only ...

Multi-Class Cost-Constrained Random Coding for Correlated Sources over the Multiple-Access Channel

open access: yesEntropy, 2021
This paper studies a generalized version of multi-class cost-constrained random-coding ensemble with multiple auxiliary costs for the transmission of N correlated sources over an N-user multiple-access channel.

Non-Adaptive Distributed Compression in Networks [PDF]

open access: yes, 2013
In this paper, we discuss non-adaptive distributed compression of inter-node correlated real-valued messages. To do so, we discuss the performance of conventional packet forwarding via routing, in terms of the total network load versus the resulting ...

Successive Wyner-Ziv Coding Scheme and its Application to the Quadratic Gaussian CEO Problem

open access: yes, 2006
We introduce a distributed source coding scheme called successive Wyner-Ziv coding. We show that any point in the rate region of the quadratic Gaussian CEO problem can be achieved via the successive Wyner-Ziv coding.

Jointly Optimized Design of Distributed Goppa Codes and Decoding [PDF]

open access: yesRadioengineering, 2023
In order to improve the adverse influence of fading channel in communication system, a distributed Goppa coding scheme is proposed in this paper. Two Goppa codes are set at the source node and the relay node in this scheme respectively. An optimal design

Quantization for Robust Distributed Coding

open access: yesInternational Journal of Distributed Sensor Networks, 2016
A distributed source coding approach is proposed for robust data communications in sensor networks. When sensor measurements are quantized, possible correlations between the measurements can be exploited to reduce the overall rate of communication ...

On a Class of Multi-Source Distributed Storage With Exact Repair

open access: yesIEEE Access, 2018
In future communication networks, say 5G networks and Internet of Things, users may need to obtain messages from multiple available sources in a distributed manner, which requires distributed storage in the network.

Distributed Quantization for Partially Cooperating Sensors Using the Information Bottleneck Method

open access: yesEntropy, 2022
This paper addresses the optimization of distributed compression in a sensor network with partial cooperation among sensors. The widely known Chief Executive Officer (CEO) problem, where each sensor has to compress its measurements locally in order to ...
