Low-Density Parity-Check codes for asymmetric distributed source coding [PDF]
2010 IEEE International Conference on Information Theory and Information Security, 2010 Low-Density Parity-Check (LDPC) codes achieve good performance, tending towards the Slepian-Wolf bound, when used as channel codes in Distributed Source Coding (DSC). Most LDPC codes found in literature are designed assuming random distribution of transmission errors.

Distributed Source Coding using Abelian Group Codes
, 2008 In this work, we consider a distributed source coding problem with a joint distortion criterion depending on the sources and the reconstruction. This includes as a special case the problem of computing a function of the sources to within some distortion and also the classic Slepian-Wolf problem, Berger-Tung problem, Wyner-Ziv problem, Yeung-Berger ...

Upper Bound on the Joint Entropy of Correlated Sources Encoded by Good Lattices
Entropy, 2019 Lattices provide useful structure for distributed coding of correlated sources. A common lattice encoder construction is to first round an observed sequence to a ‘fine’ lattice with dither, then produce the result’s modulo to a ‘ ...

Guessing with Distributed Encoders
Entropy, 2019 Two correlated sources emit a pair of sequences, each of which is observed by a different encoder. Each encoder produces a rate-limited description of the sequence it observes, and the two descriptions are presented to a guessing device that repeatedly ...

Distributed Source Coding in Dense Sensor Networks
Data Compression Conference, 2005 We study the problem of the reconstruction of a Gaussian field defined in [0,1] using N sensors deployed at regular intervals. The goal is to quantify the total data rate required for the reconstruction of the field with a given mean square distortion. We consider a class of two-stage mechanisms which a) send information to allow the reconstruction of ...

A Multicast Algorithm for Wireless Sensor Networks Based on Network Coding
International Journal of Distributed Sensor Networks, 2014 We propose a set of distributed algorithms for improving the multicast throughput in wireless sensor networks. To this end, network coding is applied when exploiting path diversity with two disjoint paths to each multicast group receiver.

Hybrid Spatial Modulation Aided Distributed Relays: Threshold Detection and Constellation Rotation
IEEE Access, 2017 In this paper, the hybrid spatial modulation (SM) aided virtual multiple-input multiple-output one-way and two-way relaying architectures with multiple distributed single-antenna relay nodes are studied.

Rate-adaptive BCH codes for distributed source coding
EURASIP Journal on Advances in Signal Processing, 2013 This paper considers Bose-Chaudhuri-Hocquenghem (BCH) codes for distributed source coding. A feedback channel is employed to adapt the rate of the code during the decoding process. The focus is on codes with short block lengths for independently coding a binary source X and decoding it given its correlated side information Y.

Interleaving Gains for Receive Diversity Schemes of Distributed Turbo Codes in Wireless Half–Duplex Relay Channels [PDF]
Radioengineering, 2015 This paper proposes the interleaving gain in two different distributed turbo-coding schemes: Distributed Turbo Codes (DTC) and Distributed Multiple Turbo Codes (DMTC) for half-duplex relay system as an extension of our previous work on turbo coding ...
