Abstract :
A method for the minimization of mean square error of the instantaneous frequency estimation using time-frequency distributions, in the case of a discrete optimization parameter, is presented. It does not require knowledge of the estimation bias. The method is illustrated on the adaptive window length determination in the Wigner distribution.
