Abstract
The problem of estimating the power spectrum from uncertain and limited autocorrelation values is considered in this paper. It is proposed that in order to reduce noise effects in the estimate, oversampling of the available time domain of the data be carried out. The oversampling problem is discussed within a new framework, with a maximum entropy algorithm appropriate to the case when a smoothness property of the power spectrum is required.
