Design of 2-band orthogonal near-symmetric CQF
نویسندگان
چکیده
The FIR 2-band wavelets have found wide applications in practice. One of their disadvantages, however, is that they cannot be made both symmetric and orthogonal. There have been some works on filters which are orthogonal and nearly symmetric. In this paper, Gröbner methods are used to design orthogonal filters with a subset of exactly symmetric coefficients of various lengths, as opposed to nearly symmetric coefficients.

A Study on Conjugate Quadrature Filters
It is very important for generating an orthonormal multiwavelet system to construct a conjugate quadrature filter (CQF). In this paper, a general method of constructing a length-J + 1 CQF with multiplicity r and scale a from a length-J CQF is obtained. As a special case, we study generally the construction of a length-J + 1 CQF with multiplicity 2 and scale 2 which can generate a compactly supp...
متن کاملSymmetric Nearly Orthogonal and Orthogonal Nearly Symmetric Wavelets
In this paper we discuss the designs of 2-channel orthogonal near symmetric wavelets on the one hand, and the symmetric near orthogonal wavelets on the other. In both types of wavelets we use the Gröbner bases design approach and present examples of both cases. ةــصلاخلا ةهج نم نيتانـق تاذ ةلـثامتملا هبش ةدماعتملا ةريّـغصلا تاجوملا ميمصت ثحبلا اذه يف شـقانـنُ فوس تاجوملا يعون لاك يف لمعتسن فوسو ....
متن کاملBuckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
متن کاملAn Algorithm for the Construction of Symmetric and Anti-Symmetric M-Band Wavelets
In this paper, we give an algorithm to construct semi-orthogonal symmetric and anti-symmetric M-band wavelets. As an application, some semi-orthogonal symmetric and anti-symmetric M-band spline wavelets are constructed explicitly. Also we show that if we want to construct symmetric or anti-symmetric M-band wavelets from a multiresolution, then that multiresolution has a symmetric scaling function.
متن کاملHigh-order balanced M-band orthogonal multiwavelet: Construction and application
This article proposed an approach to construct high-order balanced M-band (M>2) orthogonal multiwavelets with symmetric property, and demonstrated the advantages of our constructed multiwavelet systems in digital elevation model (DEM) generalization application over some other wavelet systems. We studied the theories related to the key properties of M-band multiwavelets, such as orthogonality, ...
