Abstract
This paper considers biorthogonal maximally decimated uniform filter banks as subband coders. Subject to assumptions of optimum bit allocation and whi te decorrelated quantizer distortion, it derives the filter bank that maxim izes the coding gain. Ingredients to the solution include design techniques developed by Vaidyanathan for optimal orthonormal subband coders and a gen eralization of the half whitening process that is known to maximize the cod ing gain of 1-channel biorthogonal filter banks.
