Time-Frequency Domain Fundamental Frequency Estimation and Localization of Quasiperiodic, Pulsatic Signal in a Correlated Mixture

Salehin, S.M.Akramus; Abhayapala, Thushara


We propose a method for estimating the fundamental frequency and localizing a pulsatic, quasiperiodic signal in a correlated mixture. The spectra of the correlated signal is obtained by using the short-time Fourier transform (STFT). For a quasiperiodic, pulsatic signal, the frequency signal variation over the frame index is itself quasiperiodic and pulsatic. In a mixture, the overlap of the spectra of the second signal can erase this quasiperiodic and pulsatic property for a subset of frequency...[Show more]
