Shannon rate distortion theory
WebbIn Shannon information theory, rate-distortion theory is investigated for lossy data compression, whose essence is mutual information minimization under the constraint of a certain distortion. However, in some cases involved with distortion, small probability events containing more message importance require higher reliability than those with … Webb24 aug. 2011 · The rate-distortion theorem gives the ultimate limits on lossy data compression, and the source-channel separation theorem implies that a two-stage …

Webbthe rate-distortion region was characterized for the special setting in which no secret key is available. Later, in “Rate-Distortion Theory for the Shannon Cipher System” [12], Yamamoto considered the exact problem we have heretofore described, but only obtained an inner and outer bound on the achievable rate-key-distortion region.1 In this ...
WebbThis 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. how many shingles to cover a roofWebb1 okt. 2015 · This results in an expression for the minimal possible distortion achievable under any analog-to-digital conversion scheme involving uniform sampling and linear filtering. These results thus unify the Shannon-Whittaker-Kotelnikov sampling theorem and Shannon rate-distortion theory for Gaussian sources. how did john the baptist baptize jesusWebbto as rate distortion theory, was developed by Shannon [50], [11], [21].
