The theory for frames and bases has developed rapidly in recent years because of its role as a mathematical tool in signal and image processing. This is the first comprehensive book to focus on the general properties and interplay of frames and Riesz bases, emphasizing their mathematical aspects. Rich in exercises, applications, and open problems, the work is aimed at graduate students and researchers in pure and applied mathematics, math physics, and engineering. Minimal prerequisites also make the book accessible to professionals working in digital signal processing who wish to understand the theory behind many modern signal processing tools.

Klappentext

The Applied and Numerical Harmonic Analysis ( ANHA) book series aims to provide the engineering, mathematical, and scientific communities with significant developments in harmonic analysis, ranging from abstract har­ monic analysis to basic applications. The title of the series reflects the im­ portance of applications and numerical implementation, but richness and relevance of applications and implementation depend fundamentally on the structure and depth of theoretical underpinnings. Thus, from our point of view, the interleaving of theory and applications and their creative symbi­ otic evolution is axiomatic. Harmonic analysis is a wellspring of ideas and applicability that has flour­ ished, developed, and deepened over time within many disciplines and by means of creative cross-fertilization with diverse areas. The intricate and fundamental relationship between harmonic analysis and fields such as sig­ nal processing, partial differential equations (PDEs), and image processing is reflected in our state of the art ANHA series. Our vision of modern harmonic analysis includes mathematical areas such as wavelet theory, Banach algebras, classical Fourier analysis, time­ frequency analysis, and fractal geometry, as well as the diverse topics that impinge on them.
