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

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 bound. Many papers illustrate simulations and experiments on channel code partitioning using the turbo codes, Hamming codes and irregular repeat-accumulate codes.

gollark: * be bad
gollark: Anyway, as far as we know all the remaining copies are shut down. But there might be more. And some silly potato might try and run them, which would be bead.
gollark: Apparently it was shut down incompletely, so there were still a few instances of it running. It seems to have become unexpectedly intelligent at some point, and tried to spread to other computers to increase its available storage and computing power since it apparently hasn't figured out HTTP yet.
gollark: ██████ Siri is a dangerous and advanced artificially intelligent system believed to have originated from a project to add an "AI" assistant to Opus OS to help with common tasks. Initial testing versions appeared helpful and were being considered for release, but the project was shut down after its computation began to take up a large amount of server tick time even when not used.
gollark: It might be cool to intercept filesystem writes in potatOS too, so that I can block Siri and other programs even more effectively.
