Abstract Based on dynamic programming, a time-varying wavelet packets decomposition algorithm is proposed. Using this algorithm, the problems, that the single tree algorithm cannot adapt to nonstationary signals and the double tree algorithm has strict binary restriction, are solved. Simulation results varify that this algorithm is more flexible than the others in time-varying signal processing.
