DISCUS is an acronym for ''Distributed Source Coding Using Syndromes''. INTRODUCTION DISCUS is a particular scheme used in Source Coding which is designed to achieve the Slepian-Wolf Bound 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''. PRINCIPLE DISCUS is a source coding scheme for correlated sources, which are common in the case of sensor readings from a dense group of Wireless Sensor Networks . DISCUS tries to model a particular source correlation as a channel noise, and tries to find a channel code that performs well for this channel noise. This channel code, is then proved to be the best code that can perform as a source code for the correlated data sources. 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 . |
