View source for DISCUS

'''DISCUS''', or '''distributed source coding using syndromes''', is a method for [[Distributed source coding|distributed source coding]]. It is a compression algorithm used to compress correlated data sources.  The method is designed to achieve the [[Slepian–Wolf coding|Slepian–Wolf bound]] by using channel codes.

==History==

DISCUS was invented by researchers S. S.  Pradhan and K. Ramachandran, and first published in their
paper "Distributed source coding using syndromes (DISCUS): design and construction",
published in the  ''IEEE Transactions on Information Theory'' in 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 coding|Slepian–Wolf bound]]. Many papers illustrate simulations and experiments on channel code partitioning using the turbo codes, [[Hamming code]]s and irregular repeat-accumulate codes.
