Near-capacity dirty-paper code design : a source-channel coding approach [PDF]

, 2009
This paper examines near-capacity dirty-paper code designs based on source-channel coding. We first point out that the performance loss in signal-to-noise ratio (SNR) in our code designs can be broken into the sum of the packing loss from channel coding ...

Two-Dimensional Iterative Source-Channel Decoding for Distributed Video Coding [PDF]

, 2014
Motivated by the Joint Source-Channel Decoding (JSCD) principle of exploiting the source redundancy, in this treatise we study the application of iterative source-channel decoding (ISCD) conceived for distributed video coding (DVC), where the video ...

Repair Rates for Multiple Descriptions on Distributed Storage

Entropy, 2022
In a traditional distributed storage system, a source can be restored perfectly when a certain subset of servers is contacted. The coding is independent of the contents of the source.

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 ...

Improved Deep Distributed Light Field Coding

IEEE Open Journal of Circuits and Systems, 2021
Light fields enable increasing the degree of realism and immersion of visual experience by capturing a scene with a higher number of dimensions than conventional 2D imaging.

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 ...

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

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,

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.

EXIT-chart Aided Joint Source-Coding, Channel-Coding and Modulation Design for Two-Way Relaying [PDF]

, 2013
In this contribution, we have proposed and investigated an attractive Joint Source-coding, Channel coding and Modulation (JSCM) scheme for a two-way relaying system.

Rate-Distortion Analysis of Distributed Indirect Source Coding

Entropy
Motivated by task-oriented semantic communication and distributed learning systems, this paper studies a distributed indirect source coding problem where M correlated sources are independently encoded for a central decoder.
