In this paper, a novel way to design biorthogonal filter banks and wavelets is proposed. Perfect reconstruction (PR) filter banks are roughly separated into orthogonal (paraunitary) and biorthogonal filter banks. Biorthogonal filter banks have more degrees of freedom than orthogonal ones. Thus they
