To develop a computational method capable of identifying hidden harmonic components in noisy signals by extending data beyond the observation window.
Formulated a signal processing framework based on nonlinear extrapolation beyond the measured data interval.
Implemented an adaptive algorithm designed to suppress spectral noise components during the extrapolation process.
Successfully extracted harmonic periodicities obscured by background noise.
Demonstrated adaptive reduction of noise-induced spectral components without destroying underlying signal periodicity.
