Shannon's source coding theorem
WebbClaude Shannon established the two core results of classical information theory in his landmark 1948 paper. The two central problems that he solved were: 1. How much can a message be compressed; i.e., how redundant is the information? This question is answered by the “source coding theorem,” also called the “noiseless coding theorem.” 2. WebbShannon’s Channel Coding Theorem Theorem(Shanon’sChannelCodingTheorem) For every channel , there exists a constant C = C() , such that for all 06 R < C, there exists n 0, such …

WebbAbout this book. Source coding theory has as its goal the characterization of the optimal performance achievable in idealized communication systems which must code an information source for transmission over a digital communication or storage channel for transmission to a user. The user must decode the information into a form that is a good ...
