[edit] 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.

[edit] 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.

[edit] 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.
