چکیده
Since the extension principles of constructing wavelet frames were presented, a lot of symmetric and compactly supported wavelet frames with high vanishing moments have been constructed. However the problem of constructing periodic wavelet frames with the help of extension principles is open. In this paper, we will construct tight periodic wavelet frames using the unitary extension principle and construct pairs of dual periodic wavelet frames using the mixed extension principle.

Construction of Periodic Wavelet Frames Generated by the Walsh Polynomials
An explicit method for the construction of a tight wavelet frame generated by the Walsh polynomials with the help of extension principles was presented by Shah (Shah, 2013). In this article, we extend the notion of wavelet frames to periodic wavelet frames generated by the Walsh polynomials on R by using extension principles. We first show that under some mild conditions, the periodization of a...
متن کاملExtension Principles for Tight Wavelet Frames of Periodic Functions
A unitary extension principle for constructing normalized tight wavelet frames of periodic functions of one or higher dimensions is established. While the wavelets are nonstationary, the method much simplifies their construction by reducing it to a matrix extension problem that involves finite rows of complex numbers. Further flexibility is achieved by reformulating the result as an oblique ext...
متن کاملA Construction of a Pairwise Orthogonal Wavelet Frames Using Polyphase Matrix
This paper surveys the progress made on pairwise orthogonal wavelet frames and comments on the construction methods. There are a few known constructions based on the unitary extension principle, a paraunitary matrix and a given modulation matrix. A polyphase matrix based construction method has been presented which satisfies the condition of unitary extension principle yielding pairwise orthogo...
متن کاملFramelets with Many Vanishing Moments
We study tight wavelet frames associated with given refinable functions which are obtained with the unitary extension principles. All possible polynomial symbols generating refinable functions and admitting framelets with a given number of vanishing moments are found. We also consider constructions of (anti)symmetric framelets generated by a symmetric refinable function. We give a few examples ...
متن کاملPairs of Dual Periodic Frames Ole Christensen and Say
Abstract. The time-frequency analysis of a signal is often performed via a series expansion arising from well-localized building blocks. Typically, the building blocks are based on frames having either Gabor or wavelet structure. In order to calculate the coefficients in the series expansion, a dual frame is needed. The purpose of the present paper is to provide constructions of dual pairs of f...
