Design of biorthogonal MRA generating wavelets matched to specified signal
M.R. Raghuveer, Joseph O. Chapa · 2002
The problem of fitting a mother wavelet to a signal such that this wavelet along with a dual generate a biorthogonal wavelet decomposition is addressed. It is shown that when the problem is addressed in the frequency domain with bandlimited scaling functions and wavelets, a simple formulation is possible. Further, a closed form sub-optimal solution is possible when the problem is broken down into a series of optimization problems. In the process of the problem formulation, a generalization of the Meyer class of wavelets to the biorthogonal case is obtained.
