I do not quite understand the difference between the CDM and FFCDM. How can I implement CDM in a program?

Why do you refer to them as "CDM" and "FFCDM", as if they are special algorithms or something? When I googled those acronyms the top four hits were your question. By "complex demodulation" I assume you are referring to quadrature downconversion. Is that right? – Jim Clay May 26 '12 at 20:13
Where did you find or hear these terms? – hotpaw2 May 26 '12 at 22:37
Actually I follow the paper in Ann Biomed Eng. 2006 Feb;34(2):326-38. Epub 2006 Feb 7. A high resolution approach to estimating time-frequency spectra and their amplitudes. Wang H, Siu K, Ju K, Chon KH. – thomas May 27 '12 at 3:35
Sounds like some domain-specific nomenclature that I'm not sure how to parse. Perhaps provide a more pointed question on what they're suggesting and what you're not getting. – Jason R May 28 '12 at 0:24
