Shannon rate distortion theory
WebbThe main cause of this trend is: According to Shannon's rate-distortion theory, a better performance is always achievable in theory by coding a block of signal (vector) instead of coding each signal individually (scalar). Vector quantization is a mapping Q from m dimensional vector space Rm into a finite subset TofRm(TcRm).

Webb1 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.

WebbInformation theory is the mathematical study of the quantification, storage, and communication of information. [1] The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s. [2] : vii The field is at the intersection of probability theory, statistics, computer science ... 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 ...
