Abstract
The time and frequency localizations of the product subband filter functions in tree structures are addressed and evaluated in this paper. The concept of progressive optimality is proposed as a new design approach. It is shown that the performance improvements are possible by using different PR-QMF banks at different nodes of a subband tree
