ABSTRACT:
A residual error based compensator for the frequency domain bias of an autoregressive spectral estimator is disclosed. LPC analysis is performed on the residual signal and a parametric PSD estimate is formed with the obtained LPC parameters. The PSD estimate of the residual signal multiplies the PSD estimate of the input signal.
