Abstract

This paper proposes an approach for recovering the orignal signal's spectrum from the spectra of a certain number of subsequenses, obtained by downsampling the original sequence. Closed-form expressions for the missing samples in terms of the known samples are obtained by exploiting the linear dependence relationship among the spectra of downsampled subsequences.
