چکیده
PARAUNITARY COSINE MODULATED PERFECT RECONSTRUCTION FILTER BANKST Yuan-Pel Lm and P. P Vaidyanathan Dept of Electrical Engineering, 116-81 California Institute of Technology Pasadena. CA 91125 In this paper, we construct two-dimensional (2D) FIR paraunitary Cosine Modulated Filter Banks (CMFB). All the analysis and synthesis filters are cosinemodulated versions of a 2D non-separable prototype; each filter consists of two shifts of the prototype. The design of the filter bank involves only the optimization of the prototype. Futhermore, the complxity of the 2D filter bank is that of the prototype plus two non-separable DCT matrices.

Two-dimensional Linear Phase Cosine Modulated Filter Banks1
A filter bank is referred to as cosine modulated when all the analysis and synthesis filters are cosine modulated versions of one or two prototypes. The one-dimensional (1D) cosine modulated filter bank (CMFB) is wellknown for low design cost and low complexity. In the application of subband coding, it is sometimes desirable that the individual filters have linear phase. In this paper, we will ...

In this paper a new type of maximally decimated FIR cosine modulated filter banks is proposed. Each analysis and synthesis filter in this filter bank has linear phase. We can design the system to have approximate reconstruction property (pseudoQMF system) or perfect reconstruction property (PR system). The filter bank is paraunitary in the PR case. Although there are 2M channels in the new syst...
متن کاملLinear Phase Cosine Modulated Maximally Decimated Filter Banks with Perfect Reconstruction
We propose a novel way to design maximally decimated FIR cosine modulated filter banks, in which each analysis and synthesis filter has linear phase. The system can be designed to have either the approximate reconstruction property (pseudoQMF system) or perfect reconstruction property (PR system). In the PR case, the system is a paraunitary filter bank. As in earlier work on cosine modulated sy...
متن کاملDesign of paraunitary oversampled cosine-modulated filter banks
In this paper we derive perfect reconstruction (PR) conditions for oversampled cosine-modulated lter banks. The results can be regarded as a generalization of the known work for critical subsampling. We show that in the over-sampled case we gain some additional degree of freedom, which can be exploited in the lter design process. This leads to PR prototypes with stopband attenuations being much...
متن کاملM-Channel Linear Phase Cosine Modulated Filter Banks with Perfect Reconstruction
A class of cosine modulated filter banks in which all the sub-band filters have linear phase is presented. It has only M bands compared to the M 2 channel structures so far reported in the literature. The filter bank uses only one prototype filter for both analysis and synthesis side and structurally guarantee perfect reconstruction property. The formulation is based on DCT-II. The necessary an...
