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