Abstract

This paper derives the discrete-time uncertainty and evaluates the time-frequency localizations of orthogonal bases. It measures and compares the localization features of known block transforms, filter banks and wavelet filters. It is emphasized that the time and frequency behaviors of basis functions should be considered simultaneously in design of block transforms and filter banks for further improvements in their applications.
