Adaptive local polynomial periodogram for time-varying frequency estimation

Katkovnik Vladimir (IEEE, Piscataway, NJ, United States, 1996)

The local polynomial periodogram enables one to obtain nonparametric estimates of the instantaneous frequency (IF) and its derivatives. The optimal choice of the window size based on asymptotic formulas for the variance ...
