Non-uniform sub-band decomposition for broadband equalization

To improve the convergence performance of the adaptive filtering and avoid excessive sub-band decomposition, sub-band decomposition method to decompose the whole band based on the autocorrelation matrix eigenvalue of the signal is proposed. Performance analysis demonstrates that, comparing with traditional algorithms, the proposed method can efficiently perform better with an equal number of sub-bands and with the same performance the proposed decomposition method needs less number of sub-bands and has a simpler equalization structure.
