Lag windowing
Encyclopedia
Lag windowing is a technique that consists of windowing the auto-correlation coefficients prior to estimating Linear prediction
coefficients (LPC). The windowing in the auto-correlation domain has the same effect as a convolution (smoothing) in the power spectral domain and helps stabilizing the result of the Levinson-Durbin algorithm. The window function is typically a Gaussian function.
