On ladder structures and linear phase conditions for bi-orthogonal filter banks

چکیده
In this paper some new results for multidimensional m-band bi-orthogonal lter banks are presented. In the rst part of the paper we introduce the ladder structure as a method for the design and implementation of afore-mentioned lter banks. The second part of the paper fo-cuses upon enforcing linear phase (LP) conditions in the context of ladder structures. The formulation of the LP conditions is done with the help of a recently introduced, al-gebraicly oriented method for describing multidimensional lter banks. It is shown that in this notation, ladder structures allow a natural formulation of LP conditions.

متن کاملOn -Channel Linear Phase FIR Filter Banks and Application in Image Compression
This paper investigates the theory and structure of a large subclass of M -channel linear-phase perfect-reconstruction FIR filter banks—systems with analysis and synthesis filters of length Li = KiM + , where is an arbitrary interger, 0 < M , and Ki is any positive interger. For this subclass of systems, we first investigate the necessary conditions for the existence of linear-phase perfect-rec...
متن کاملDesign of symmetric bi-orthogonal double density wavelet filter banks
We look at the design of a class of oversampled filter banks and the resulting framelets. The oversampled property is achieved via an extra subband resulting in Double Density Filter Banks (DDFB’s). We design a class of such filters with linear phase property. We will look at a special class of framelets from a filter bank perspective, in that we will design double density filter banks (DDFB’s)...
متن کاملConstraints of Second-Order Vanishing Moments on Lattice Structures for Non-separable Orthogonal Symmetric Wavelets
In this paper, a design method of two-dimensional (2-D) orthogonal symmetric wavelets is proposed by using a lattice structure for multi-dimensional (M-D) linear-phase paraunitary filter banks (LPPUFB), which the authors have proposed as a previous work and then modified by Lu Gan et al. The derivation process for the constraints on the second-order vanishing moments is shown and some design ex...
