摘要
A method for minimization of the mean square error (MSE) 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 adaptive window width determination in the Wigner distribution.
