Balanced multiwavelets theory and design

This correspondence deals with multiwavelets which are a recent generalization of wavelets in the context of time-varying lter banks and with their applications to signal processing and especially compression. By their inherent structure, multiwavelets are t for processing multi-channel signals. This is the main issue we will be interested in here. The outline of the paper is as follow. First, we will review material on multiwavelets and their links with multiilter banks and especially time-varying lter banks. Then, we will have a close look at the problems encountered when using multiwavelets in applications and we will propose new solutions for the design of multiwavelets lter banks by introducing the so-called`balanced multiwavelets'.
