Results on Optimal Biorthogonal Filter Banks
Optimization of filter banks for specific input statistics has been of interest in the theory and practice of subband coding. For the case of orthonormal filter banks with infinite order and uniform decimation, the problem has been completely solved in recent years. For the case of biorthogonal filter banks, significant progress has been made recently, although a number of issues still remain t...
متن کاملLifting Schemes for Biorthogonal Modulated Filter Banks
In this paper we connect the design of biorthogonal modulated filter banks with the idea of lifting schemes, which were proposed for the construction of biorthogonal wavelets. Based on this formulation, we derive a lattice-like structure for the polyphase components. As the rotationbased structures for the design and implementation of paraunitary modulated filter banks, our structure automatica...
متن کاملDesign of Signal-Adapted Biorthogonal Filter Banks
A method for the design of signal-adapted, -channel biorthogonal filter banks of finite length is presented. The design problem is formulated as a constrained optimization problem and is solved by converting it into an iterative line-search problem through a first-order parameterization of the perfect reconstruction constraint. It is also shown for the two-channel case that if the analysis and ...
متن کاملTime-Varying Perfect Reconstruction Filter Banks for Finite Length Signals
A new approach to the non-expansive two band decomposition of finite length signals is introduced. The technique is based on the time-varying perfect reconstruction filter banks concept. In this approach the main analysis filter bank is instantaneously switched, at the signal boundaries, to a shorter filter bank: the D1 or Haar filter bank. The technique can be applied to all types of two band ...
متن کاملTime-Varying Filter Banks with Low Delay for Audio Coding
A design method and filter structure for fast modulated low delay filter banks is presented. The system delay can be pre-specified independent of the filter length. Perfect reconstruction is structurally guaranteed. It is shown how to make this structure time-varying, which includes switching the number of bands, while maintaining perfect reconstruction. Low delay filter banks, besides having t...
