Periodic wavelet frames and time-frequency localization
arXiv:1210.6560 · doi:10.1016/j.acha.2014.02.002
Abstract
A family of Parseval periodic wavelet frames is constructed. The family has optimal time-frequency localization (in the sense of the Breitenberger uncertainty constant) with respect to a family parameter and it has the best currently known localization with respect to a multiresolution analysis parameter.
