A seamless and smooth transition from nonparametric multitaper (MT) spectral estimation (SE) to autoregressive (AR) parametrization is made possible via autocorrelation estimates from multitapered data. We show that AR spectral estimates obtained from MT autocorrelation estimates outperform the conventional method and the Capon-AR estimates. We derive a direct method of autocorrelation estimation from multitapered data. We show that choice of tapers yields low-bias and consistent… CONTINUE READING
