Shannon theory for compressed sensing

Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems. This is based on the principle that, through optimization, the … Visa mer A common goal of the engineering field of signal processing is to reconstruct a signal from a series of sampling measurements. In general, this task is impossible because there is no way to reconstruct a signal during the times that … Visa mer Compressed sensing relies on $${\displaystyle L^{1}}$$ techniques, which several other scientific fields have used historically. In statistics, the least squares method … Visa mer The field of compressive sensing is related to several topics in signal processing and computational mathematics, such as underdetermined linear-systems Visa mer • "The Fundamentals of Compressive Sensing" Part 1, Part 2 and Part 3: video tutorial by Mark Davenport, Georgia Tech. at SigView, the IEEE Signal Processing Society Tutorial Library. • Using Math to Turn Lo-Res Datasets Into Hi-Res Samples Wired Magazine article Visa mer Underdetermined linear system An underdetermined system of linear equations has more unknowns than equations and generally has an infinite number of solutions. … Visa mer • Noiselet • Sparse approximation • Sparse coding • Low-density parity-check code Visa mer Webbcompressive sensing and information theory.

WebbL' acquisition comprimée (en anglais compressed sensing) est une technique permettant de trouver la solution la plus parcimonieuse d'un système linéaire sous-déterminé. Elle englobe non seulement les moyens pour trouver cette solution mais aussi les systèmes linéaires qui sont admissibles.

The sampling theory of Shannon can be generalized for the case of nonuniform sampling, that is, samples not taken equally spaced in time. The Shannon sampling theory for non-uniform sampling states that a band-limited signal can be perfectly reconstructed from its samples if the average sampling rate satisfies the Nyquist condition. Therefore, although uniformly spaced samples may result in easier reconstruction algorithms, it is not a necessary condition for perfec…
