Cepstral Analysis For Spectral Analysis

This is the original implementation of the cepstrum thresholding technique for nonparametric estimation of smooth spectra introduced in:
P. Stoica and N. Sandgren. Smoothed nonparametric spectral estimation via cepstrum thresholding, IEEE Sign. Proc. Mag., vol. 23, pp. 34-45, Nov 2006.
The exchange files contains another implementation by Dr. S. Lutes, but according to our experience our original implementation has better performance. Requirements:
· MATLAB Release: R13
