Autoregressive Spectral Estimation in Additive Noise
Abstract
The estimation of the spectral density of a discrete-time stationary Gaussian autoregressive (AR) process from a finite set of noisy observations is considered. A modified spectral estimator based on the high-order Yule-Walker equations is considered. Joint asymptotic normally of this spectral estimator is established; a precise asymptotic expression for the covariance matrix of the limiting distribution is obtained. The special case of AR(1) plus noise is considered in some detail. Keywords: Bearing estimation; Array processing; Statistics; Time series analysis, Reprints.
