  • Abstract
    Estimation of the instantaneous frequency (IF) of nonlinear FM signals with additive Gaussian noise is considered. An algorithm for the IF estimation is proposed based on Wigner-Ville distribution (WVD) maxima and local singular value decomposition (SVD).Simulation result shows that the proposed method is valid for nonlinear FM signals.
