  • Abstract
    A new class of cosine-modulated FIR filter banks is proposed. The necessary and sufficient condition is given which ensures that the filter banks satisfy the paraunitary and linear phase properties simultaneously. The prototype filter can be designed by optimising its stopband energy on the two-channel lattice parameters, and the filter banks can be implemented efficiently using DCT and DST
