Abstract The design method of a class of symmetric biorthogonal wavelets is proposed in this paper. The filter banks of the wavelets possess lattice structure, the analysis and synthesis filter banks for wavelets meet biorthogonality and regularly conditions, and the filters are all real binary coefficients. Therefore, the wavelet transform is suitable for high-speed VLSI implementation. Both the mathematical derivations and the design examples in the paper verify the effectiveness of proposed method.
