Résumé
Abstract

Nous construisons des paquets d'ondelettes de base uniformément bien localisés en temps et en fréquences. Les bases orthonormées correspondantes de paquets d'ondelettes sons parametrisées par des partitions dyadiques obeissants une condition de variation locale.

We construct basic wavelet packets with uniformly bounded localization in both time and frequency. The corresponding orthonormal bases of wavelet packets are parametrized by dyadic segmentations obeying a local variation condition.
