Time-varying spectrum estimation for a general class of non-stationary processes.

In a general class of nonstationary processes, the autocorrelation may have different time variation rates at different lags. The estimation of each lag in a manner consistent with its nature of nonstationarity yields a reduction in the variance of the spectrum estimate at different frequencies.
