Abstract
A method for designing wavelet filter banks that are adapted to the given signal is proposed. The method is based on optimising a certain cost function with constraint conditions. Gradient-descent optimisation techniques are not adequate for the minimisation of such a cost function. Evolutionary programming is used to resolve this difficult optimisation problem. Simulation results are given
