Cepstral Alanysis for Spectral Analysis

How to use the cepstrum for smoothed estimation of the spectrum of a stationary signal

Description

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.

• MATLAB release: MATLAB 6.5 (R13)

I'm trying to get the code to run on my laptop, but i'm not able to recognize the input data y, and also mu. Please clarify what y to use and what is mu value is needed

Phil, your email info seems to be invalid. Please contact me via the 'Contact Author' option and I will send you the requested information.

Hi, Niclas Sandgren,I also find the same problem with Phil, could you tell me what the mu vlaue is? I don't download the corresponding paper written by you,thank you very much!

[Vit Svoboda]

Hi, all. Has anybody m-file for cepstral mean subtraction (CMS) algorithm ? Thanx

I get an all-NaN result for some real-world data. What constraints do I need to obey to avoid this? Also: it would be nice to provide some input validation and a more transparent implementation.
