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 ...

Rateless Distributed Source Code Design [PDF]
Proceedings of the 5th International Mobile Multimedia Communications Conference, 2009 Over the past decade, rateless codes, i.e., digital fountain codes, have emerged as an efficient and robust solution for reliable data transmission over packet erasure networks and a particularly suitable one for multicasting and broadcasting applications where users may experience variable channel conditions and packet loss rates, such as mobile ...

Distributed Source Coding Techniques for Lossless Compression of Hyperspectral Images
EURASIP Journal on Advances in Signal Processing, 2007 This paper deals with the application of distributed source coding (DSC) theory to remote sensing image compression. Although DSC exhibits a significant potential in many application fields, up till now the results obtained on real signals fall short of

IEEE Open Journal of the Communications Society, 2021 This paper addresses the optimization of distributed compression in a sensor network. A direct communication among the sensors is not possible so that noisy measurements of a single relevant signal have to be locally compressed in order to meet the rate ...

Source Modeling for Distributed Video Coding [PDF]
IEEE Transactions on Circuits and Systems for Video Technology, 2012 This paper studies source and correlation models for Distributed Video Coding (DVC). It first considers a twostates HMM, i.e. a Gilbert-Elliott process, to model the bit-planes produced by DVC schemes. A statistical analysis shows that this model allows us to accurately capture the memory present in the video bit-planes.

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.

Polar codes for distributed hierarchical source coding
Advances in Mathematics of Communications, 2015 We show that polar codes can be used to achieve the rate-distortion functions in the problem of hierarchical source coding also known as the successive refinement problem. We also analyze the distributed version of this problem, constructing a polar coding scheme that achieves the rate distortion functions for successive refinement with side ...

Distributed Source Coding and Its Applications in Relaying-Based Transmission
IEEE Access, 2016 Distributed source coding (DSC) schemes rely on separate encoding but joint decoding of statistically dependent sources, which exhibit correlation. DSC has numerous promising applications ranging from reduced-complexity handheld video communications to ...
