We present a design of a new class of compactly supported antisymmetric biorthogonal wavelet filter banks which have the analysis as well as the synthesis filters of even-length. Here, the analysis and the synthesis filters are designed to have minimum joint duration-bandwidth localization (JDBL). The design of filters has been formulated as a direct time-domain linearly constrained eigenvalue problem...
The accurate and efficient representation of a signal in terms of elementary atoms has been a challenge in many signal processing applications including harmonic analysis. The wavelet bases have been proved to be very efficient and flexible atoms. Towards the goal of obtaining optimal wavelet bases, we present a simple and efficient parametrization technique for constructing linear phase biorthogonal...
