Estimation of sinusoidal frequency-modulated signal parameters in high-noise environment

Abstract

In this paper, we consider the estimation of the sinusoidal frequency-modulated (FM) signal parameters in high-noise environments. For this purpose, we have combined the Viterbi algorithm for the estimation of the instantaneous frequency with the recently proposed technique for the parametric estimation of the FM signals based on the short-time Fourier transform. The proposed technique gives the accurate parameters estimation of the Cramer–Rao lower bound for signal-to-noise ratio of −2dB.
