Undecimated Non-uniform Multivariate Empirical Mode Decomposition Filter banks for Arbitrary Nodes and its Application for Speech Enhancement Mode Decomposition Filter banks for Arbitrary

Abstract

This paper introduces a technique to build undecimated Multivariate Empirical Mode Decomposition Filter Banks (MEMDFBs) for arbitrary trees. The available option of undecimated MEMDFBs for arbitrary trees is achieved by exchanging assisting noise channels. An application for speech enhancement is also introduced.
