Sparse blind source separation for partially correlated sources

2014 IEEE International Conference on Image Processing (ICIP), 2014
Blind source separation (BSS) is a very popular technique to analyze data which can be modeled as linear mixtures of elementary sources. Standard approaches generally make the assumption that such sources are statistically independent or at least uncorrelated.

On joint source-channel decoding for correlated sources

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
Whenever digital communications is subject to constraints in delay and complexity, some residual redundancy remains after source coding. Shannon's separation theorem does not hold strictly and hence joint source-channel decoding is beneficial.

Sources of correlation degradation

Applied Optics, 1977
Various sources of degradation of the peak intensity and SNR of an output optical correlation are considered both theoretically and experimentally. Several methods for limiting the effect of these sources of degradation are also advanced, and experimental and theoretical data are presented.

Correlated sources with actions

2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013
In this paper, we consider the problem of distributed compression of correlated sources with action-dependent joint distribution. This setup is an extension of the Slepian Wolf model, but where actions taken by the encoder or the decoder and affect the generation of one of the sources.

Successive Coding of Correlated Sources

IEEE Transactions on Information Theory, 2007
The rate-distortion (RD) problem for two-layer coding of a pair (X,Y) of correlated sources is considered. The first layer information enables reconstruction of X within a certain distortion DX, while reception of both layers additionally enables reconstruction of Y within distortion DY.

Message authentication with correlated sources

2015 IEEE International Symposium on Information Theory (ISIT), 2015
In this paper, we study the problem of message authentication with two correlated sources observed by the legitimate transmitter and receiver as secret information. We consider an active adversary capable of the impersonation attack and the substitution attack.

Wiretap Channel with Correlated Sources

2014 IEEE International Conference on Cloud Engineering, 2014
This paper studies the problem of secret-message transmission over a wiretap channel with correlated sources in the presence of an eavesdropper who has no source observation. A coding scheme is proposed based on a careful combination of 1) Wyner-Ziv's source coding to generate secret key from correlated sources based on a certain cost on the channel, 2)

Reference Encoding of Correlated Digital Sources

IEEE Transactions on Communications, 1978
A reference code, with an associated bound on the code rate, for the encoding of correlated digital sources is introduced. The reference code is adaptive and simple to implement. Image coding results obtained using concatenated trellis and reference encoding are presented.

Predictive coding of correlated sources

Manufacturing Engineer, 2005
A lossy coding scheme is proposed for separate encoding and joint decoding of two correlated sequences. The algorithm simultaneously exploits the correlation between the sequences (using a binning-based quantization scheme) and that between the samples of each sequence (using linear prediction).
