Abstract. A review of known time-frequency estimation methods is presented. We consider a fast time-frequency estimation algorithm of single-tone complex signal. The results of the simulation algorithm are presented, the comparison with the Short-time Fourier transform and Cramer-Rao lower bound is carried out for chirp signal parameters estimation.

Keywords: time-frequency estimation, Short-time Fourier transform, parametric estimation, chirp, Cramer-Rao lower bound.
