A Comparative Evaluation of Techniques for Single-Frame Discrimination of Nonstationary Sinusoids
Jeremy J. Wells, Damian Murphy · IEEE Transactions on Audio Speech and Language Processing · 2010
Many spectral analysis and modification techniques require the separation of sinusoidal from nonsinusoidal signal components of a Fourier spectrum. Techniques exist for the estimation of the parameters of nonstationary sinusoids, and for discriminating these from other components, within a single Fourier frame. We present a comparative study of five methods for sinusoidal discrimination, considering their effectiveness and their computational cost.
