METHOD FOR SEPARATING INPUT SIGNAL

摘要

PROBLEM TO BE SOLVED: To separate a signal including a plurality of sinusoidal wave signals and a plurality of AM-FM modulated sinusoidal wave signals into components.SOLUTION: Firstly, a multi-component signal is separated by 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.
