Abstract :
The asymptotic performance of the local frequency (LF) estimator, based on the Wigner distribution (WD) of multidimensional signals, is considered. The optimal estimation window size, producing minimal mean squared error (MSE), is derived. The results are illustrated and confirmed by numerical examples.
