Spectral Smoothing and Recursion Based on the Nonstationarity of the Autocorrelation Function

Averaging and recursion in short-time spectral analysis in view of the nature of the nonstationarity of the random process is addressed. Using the Wigner spectrum estimator as a general model, this correspondence relates the selection of the time and lag windows to the stationary intervals of the au...
