Nonorthogonal wavelet approximation with rates of deterministic signals

Abstract

An nth order asymptotic expansion is produced for the L2-error in a nonorthogonal (in general) wavelet approximation at resolution 2-k of deterministic signals f. These signals over the whole real line are assumed to have n continuous derivatives of bounded variation. The engaged nonorthogonal (in general) scale function fulfills the partition of unity property, and it is of compact support.
