Frame analysis for biorthogonal cosine-modulated filterbanks
This paper addresses the efficient computation of frame bounds for cosine-modulated filterbanks. We derive explicit expressions for the eigenvalues of the frame operator that can be easily computed from the prototype's polyphase components. The number of channels and the downsampling factor may be even or odd, and the oversampling factor is supposed to be an integer. The analysis of low-delay, ...
متن کاملE$cient biorthogonal cosine-modulated "lter banks
Biorthogonal modulated "lter banks, when compared to paraunitary ones, provide the advantage that the overall system delay can be chosen independently of the "lter length, thus allowing to design low delay "lter banks. They have recently been studied by several authors. In this paper, we connect two di!erent design methods, namely the quadratic constrained least-squares optimization and the pri...
متن کامل-Channel Compactly Supported Biorthogonal Cosine-Modulated Wavelet Bases
In this correspondence, we generalize the theory of compactly supported biorthogonal two-channel wavelet bases to M -channel. A sufficient condition for the M -channel perfect reconstruction filter banks to constructM -channel biorthogonal bases of compactly supported wavelets is derived. It is shown that the construction of biorthogonal M -channel wavelet bases is equivalent to the design of a...

متن کاملBiorthogonal cosine-modulated filter banks without DC leakage
In this paper, we present a structure for implementing the polyphase filters of biorthogonal modulated filter banks that automatically guarantees perfect reconstruction of the filter bank and furthermore allows to specifiy the values of the filters’ frequency responses at certain frequencies. Thus, modulated filter banks without DC leakage can be designed. The new stucture is based on lifting s...
