A 3-node lossy source coding problem for a 2-DMS(X1, X2) is considered. Source nodes 1 and 2 observe X1 and X2, respectively, and each wishes to reconstruct the other source with a prescribed distorti...
We investigate distributed source coding of two correlated sources X and Y where messages are passed to a decoder in a cascade fashion. The encoder of X sends a message at rate R1 to the encoder of Y....
Source Coding With Limited-Look-Ahead Side Information at the Decoder
Causal source codes delay-constrained coding Gel’fand–Pinsker channel rate distortion function Slepian–Wolf coding Wyner–Ziv coding

We characterize the rate distortion function for the source coding with decoder side information setting when the ith reconstruction symbol is allowed to depend only on the first i + `side information...

We study a new encoding scheme for lossy source compression based on spatially coupled low-density generator-matrix codes. We develop a belief-propagation guided-decimation algorithm, and show that th...
Non-equilibrium Information Envelopes and the Capacity-Delay-Error-Tradeoff of Source Coding
Non-equilibrium Information Envelopes Capacity-Delay-Error-Tradeoff Source Coding Information Theory

Abstract: This paper develops an envelope-based approach to establish a link between information and queueing theory. Unlike classical, equilibrium information theory, information envelopes focus on t...
The penalty incurred by imposing a finite delay constraint in lossless source coding of a memoryless source is investigated.
A statistical-mechanical view on source coding: physical compression and data compression
statistical-mechanical physical compression data compression
2010/11/23
We draw a certain analogy between the classical information–theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a c...
A new sufficient condition for sum-rate tightness in quadratic Gaussian multiterminal source coding
sufficient condition sum-rate tightness quadratic Gaussian multiterminal source coding
2010/12/3
This work considers the quadratic Gaussian multiterminal (MT) source coding problem and provides a new sufficient condition for the Berger-Tung sum-rate bound to be tight. The converse proof utilizes ...

2010/12/9
This paper investigates the problem of secure lossy source coding in the presence of an eavesdropper with arbitrary correlated side informations at the legitimate decoder (referred to as Bob) and the ...
