Review of Recent Results on Optimal Orthonormal Subband Coders.

Abstract

The conditions for optimality of uniform orthonormal subband coders are reviewed. A number of properties of optimal filter banks are then summarized. The case of nonuniform orthonormal filter banks is also considered, and it is shown that the well known connection between optimal coding gain, energy compaction, and principal component property does not extend to the nonuniform case.
