Variable-Rate Universal Slepian-Wolf Coding with Feedback [PDF]

open access: yesConference Record of the Thirty-Ninth Asilomar Conference onSignals, Systems and Computers, 2005., 2006
Traditional Slepian-Wolf coding assumes known statistics and relies on asymptotically long sequences. However, in practice the statistics are unknown, and the input sequences are of finite length. In this finite regime, we must allow a non-zero probability of codeword error isin and also pay a penalty by adding redundant bits in the encoding process ...

Asymmetric Joint Source-Channel Coding for Correlated Sources with Blind HMM Estimation at the Receiver

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
We consider the case of two correlated sources, and . The correlation between them has memory, and it is modelled by a hidden Markov chain. The paper studies the problem of reliable communication of the information sent by the source over an additive ...

A Mutual Algorithm for Optimizing Distributed Source Coding in Wireless Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2012
Wireless Sensor Networks (WSNs) are composed of small wireless nodes equipped with sensors, a processor, and a radio communication unit, all normally powered by batteries.

Are Slepian-Wolf Rates Necessary for Distributed Parameter Estimation?

open access: yes, 2015
We consider a distributed parameter estimation problem, in which multiple terminals send messages related to their local observations using limited rates to a fusion center who will obtain an estimate of a parameter related to observations of all ...

Kolmogorov complexity version of Slepian-Wolf coding [PDF]

open access: yesProceedings of the 49th Annual ACM SIGACT Symposium on Theory of Computing, 2017
Alice and Bob are given two correlated n-bit strings x_1 and, respectively, x_2, which they want to losslessly compress and send to Zack. They can either collaborate by sharing their strings, or work separately. We show that there is no disadvantage in the second scenario: Alice and Bob, without knowing the other party's string, can achieve almost ...

The Three-User Finite-Field Multi-Way Relay Channel with Correlated Sources

open access: yes, 2013
This paper studies the three-user finite-field multi-way relay channel, where the users exchange messages via a relay. The messages are arbitrarily correlated, and the finite-field channel is linear and is subject to additive noise of arbitrary ...

Code Design for the Noisy Slepian-Wolf Problem [PDF]

open access: yesIEEE Transactions on Communications, 2013
We consider a noisy Slepian-Wolf problem where two correlated sources are separately encoded (using codes of fixed rate) and transmitted over two independent binary memoryless symmetric channels. The capacity of each channel is characterized by a single parameter which is not known at the transmitter.

A Decision Feedback Based Scheme for Slepian-Wolf Coding of sources with Hidden Markov Correlation

open access: yes, 2005
We consider the problem of compression of two memoryless binary sources, the correlation between which is defined by a Hidden Markov Model (HMM). We propose a Decision Feedback (DF) based scheme which when used with low density parity check codes results

Polynomial complexity of polar codes for non-binary alphabets, key agreement and Slepian-Wolf coding

open access: yes, 2014
We consider polar codes for memoryless sources with side information and show that the blocklength, construction, encoding and decoding complexities are bounded by a polynomial of the reciprocal of the gap between the compression rate and the conditional
