Reversible Resampling of Integer Signals
Work presents ground-breaking theoretical work which improved and corrected a previously accepted theory in signal processing. Till the publication of this paper, it was believed that original samples could not be losslessly recovered from the resampled data except in some extremely special cases, because strong attenuation of high frequencies occurs after interpolation. It is proved that signal resampling based on polynomial interpolation can be reversible even for integer signals, i.e., the original signal can be reconstructed losslessly from the resampled data. In addition, a method using elegant matrix factorization is introduced for reversible uniform scaled and shifted resampling.
