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

History
[edit]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
[edit]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.
