A new class of alternative dual frames is introduced in the setting of finite frames for Rd. These dual frames, called Sobolev duals, provide a high precision linear reconstruction procedure forâ€¦ (More)

The compressed sensing problem for redundant dictionaries aims to use a small number of linear measurements to represent signals that are sparse with respect to a general dictionary. Under anâ€¦ (More)

The K-level Sigma-Delta (/spl Sigma//spl Delta/) scheme with step size /spl delta/ is introduced as a technique for quantizing finite frame expansions for /spl Ropf//sup d/. Error estimates forâ€¦ (More)

Consistent reconstruction is a method for producing an estimate x âˆˆ R d of a signal x âˆˆ R d if one is given a collection of N noisy linear measurements q n = x, Ï• n +Ç« n , 1 â‰¤ n â‰¤ N , that have beenâ€¦ (More)
