The Information Processing Group is concerned with fundamental issues in the area of communications, in particular coding and information theory. Information theory establishes the limits of communications – what is achievable and what is not. Coding theory tries to devise low complexity schemes that approach these limits. The group is composed of five laboratories : Communication Theory Laboratory (LTHC), Information Theory Laboratory (LTHI), Laboratory for Information in Networked Systems (LINX), Laboratory for Statistical Mechanics of Inference in Large Systems (SMILS), and Prof. Shkel’s Group (UPSHKEL).
