Local AM/FM Parameters Estimation: Application to Sinusoidal Modeling and Blind Audio Source Separation.
IEEE Signal Processing Letters(2018)
摘要
This letter extends our recently introduced method which was designed to estimate instantaneous frequency and chirp rate of linearly modulated signals. Indeed, we derive several new estimators related to our previous ones which provide in the time-frequency plane all the signal parameters of the investigated model: amplitude, frequency, and their local modulations (AM/FM). Our estimators are first...
