Distributed coding of sources with bursty correlation [PDF]
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012 This paper focuses on the performance of a Wyner-Ziv coding scheme for which the correlation between the source and the side information is modeled by a hidden Markov model with Gaussian emission. Such a signal model takes the memory of the correlation into account and is hence able to describe the bursty nature of the correlation between sources in ...

Distributed Hypothesis Testing over a Noisy Channel: Error-Exponents Trade-Off
Entropy, 2023 A two-terminal distributed binary hypothesis testing problem over a noisy channel is studied. The two terminals, called the observer and the decision maker, each has access to n independent and identically distributed samples, denoted by U and V ...

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

EURASIP 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,

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

Rate-adaptive BCH codes for distributed source coding [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 This paper considers Bose-Chaudhuri-Hocquenghem (BCH) codes for distributed source coding. A feedback channel is employed to adapt the rate of the code during the decoding process. The focus is on codes with short block lengths for independently coding a binary source X and decoding it given its correlated side information Y.

Quantization for Robust Distributed Coding
International 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 ...

Distributed Quantization for Partially Cooperating Sensors Using the Information Bottleneck Method
Entropy, 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 ...
