Inter-component Phase Processing of Quasipolyharmonic Signals

Abstract

The paper presents a generalization of theoretical and experimental research in the field of inter-component phase signal processing based on instantaneous phase estimates of multiple or rational frequency harmonic components. We propose to model harmonic phase of each component of quasipolyharmonic signal with consideration of relative delays that occur on different frequencies during the signal propagation. Based on the proposed harmonic phase model, it is argued the inter-component phase relations carry the information about parameters of these relative delays.
