DISCUS is an acronym for Distributed Source Coding Using Syndromes.
Introduction
DISCUS is a compression algorithm used to compress correlated data sources.
DISCUS is a particular scheme used in source coding which is designed to achieve the Slepian-Wolf bound (David Slepian) by using channel codes.
History
DISCUS was invented by researchers SS Pradhan and K Ramachandran, in their seminal paper Distributed source coding using syndromes (DISCUS): design and construction published in the Information Theory, IEEE Transactions on, 2003.
Variations
Many variations of DISCUS are presented in related literature. One such popular scheme is the Channel Code Partitioning scheme, which is an a-priori scheme, to reach the Slepian-Wolf bound. Many papers illustrate simulations and experiments on channel code partitioning using the turbo codes, Hamming codes and Irregular Repeat Accumulate Codes.
