Estimation. <inria-00001059> (original) (raw)
Any time-frequency representation of a signal contains cru- cial information on the characteristics of the signal. In this paper we deal with the estimation of the instantaneous fre- quency of signals corrupted by additive noise. We propose a robust instantaneous frequency's estimation procedure based on the use of the computation of a time-frequency represen- tation of the analyzed signal, followed
