General synthesis procedures for FIR lossless transfer matrices, for perfect-reconstruction multirate filter bank applications
A recently reported procedure for the design of M-channe1 perfect-reconstruction quadrature mirror filter banks uses the concept of “lossless alias-component matrices.” The synthesis of such QMF banks centers around the generation of a lossless M X M FIR transfer matrix E ( z ) . Recent results for such generation have been somewhat ad hoc, Le., not sufficiently general. In this paper, a genera...

متن کاملTwo Dimensional Mri Image Analysis by Using Oversampled Fir Filter Bank for Perfect Reconstruction
In this paper we propose oversampled three channels FIR filter banks [FB]. Channels are selected likewise which gives the result near perfect reconstruction filter bank. The inband aliasing is significantly reduced by selecting proper frequency spectrum and design of filters of filter banks. This design gives the result of oversampled FIR filter bank for two dimensional MRI image with peak sign...
متن کاملTwo Channel Perfect Reconstruction Multirate Filter Bank Based on Linear Canonical Transform
The multirate digital signal processing (DSP) is required in digital system where more than one sampling rate is required. In this paper, we propose the two channel (2dimensional) perfect reconstruction multirate filter bank, which is based on the linear canonical transform. The main motivation is the fact that Linear Canonical Transform (LCT) provides a general mathematical tool with very broa...
متن کاملAlgorithms for Optimal Multirate Filter Bank Design
This paper is concerned with the problem of designing optimal multirate lter banks. Three design criteria are considered for linear phase FIR lter banks: H 2 measure, H 1 and the mixture of them. A closed-form solution is presented for optimal H 2 lter bank design. For optimal H 1 lter bank design, two algorithms are given which involve solving the design problem using positive semi-deenite pro...
