Book excerpt: Source coding or lossy data compression has been extensively studied ever since Shan- non formally described the problem more than half of a century ago. Yet source coding schemes approaching the theoretical Shannon limit even on simple stationary sources such as IID Gaussian or IID uniform sources remain elusive. In this dissertation, both source coding and the related rate-constrained simulation problem are studied. Four necessary conditions for asymptotically optimal sliding-block or stationary codes for source coding and rate-constrained simulation are derived. The first two necessary conditions are proved for stationary ergodic sources while the remaining two necessary conditions are proved for IID sources. A new code design algorithm which attempts to satisfy all four necessary conditions is presented. The code structure has intuitive similarities to classic random coding arguments as well as to "fake process" methods and alphabet-constrained methods. Experimental results show that the new coding design algorithm provides comparable or superior performance with respect to previously published methods on common IID and autoregressive examples, often by significant margins. In many cases, such as IID Gaussian, IID uniform and discrete IID binary sources, the performance approaches the theoretical Shannon limit.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated version of the information theory classic, first published in 1990. About one-third of the book is devoted to Shannon source and channel coding theorems; the remainder addresses sources, channels, and codes and on information and distortion measures and their properties. New in this edition: Expanded treatment of stationary or sliding-block codes and their relations to traditional block codes Expanded discussion of results from ergodic theory relevant to information theory Expanded treatment of B-processes -- processes formed by stationary coding memoryless sources New material on trading off information and distortion, including the Marton inequality New material on the properties of optimal and asymptotically optimal source codes New material on the relationships of source coding and rate-constrained simulation or modeling of random processes Significant material not covered in other information theory texts includes stationary/sliding-block codes, a geometric view of information theory provided by process distance measures, and general Shannon coding theorems for asymptotic mean stationary sources, which may be neither ergodic nor stationary, and d-bar continuous channels.

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the theory of probabilistic information measures and their application to coding theorems for information sources and noisy channels. The eventual goal is a general development of Shannon's mathematical theory of communication, but much of the space is devoted to the tools and methods required to prove the Shannon coding theorems. These tools form an area common to ergodic theory and information theory and comprise several quantitative notions of the information in random variables, random processes, and dynamical systems. Examples are entropy, mutual information, conditional entropy, conditional information, and discrimination or relative entropy, along with the limiting normalized versions of these quantities such as entropy rate and information rate. Much of the book is concerned with their properties, especially the long term asymptotic behavior of sample information and expected information. This is the only up-to-date treatment of traditional information theory emphasizing ergodic theory.
