Unbiased ACS Estimates may lead to negative spectral estimates
in [Matlab]

From: Thu on 11 May 2010 06:14 Hi all, I am researching about autocorrelation sequence estimation.I read a book named "Introduction to Spectral Analysis" that written by Petre Stoica. It is stated in chapter 2 that if unbiased ACS estimates ( autocorrelation sequence) are used in the correlogram spectral estimate, then negative spectral estimates may results. Could you help me to give an example data sequence that gives such a negative spectral estimate. I am really a beginner of this research domain, so please help me to understand it more. Thank you!!!!
