Method for Separating Multi-Component Signals

摘要

A method separates a multi-component signal by first estimating parameters of the signal. Then, using periodicity-based algebraic separation and energy-based demodulation, the signal is separated into components according to the parameters and constraints. Last, a Teager-Kaiser energy detector is applied to each component to provide a direct current signal for each component, and the constraint for each component used by the separating.

1. A method for separating an input signal, wherein the input signal is a multi-component signal, comprising the steps of:
estimating parameters of the input signal; separating the input signal, using periodicity-based algebraic separation and energy-based demodulation (PASED), into components according to the parameters and constraints; and applying a Teager-Kaiser energy detector (TKED) to each component to provide a direct current (DC) signal for each component, and the constraint for each component used by the separating, wherein the steps are performed in a processor.
