Abstract
A filter structure based on a modified autoregressive approach is introduced. It is shown that this structure corresponds to the estimate obtained by the Pisarenko harmonic decomposition method. The case of a real sinusoidal signal embedded in white Gaussian noise is analyzed in detail. The frequency of the sinusoid is directly related to a single parameter. An adaptive approach is used to estimate this parameter
