• Marques and Almeida (ICASSP 1986, p1233): Using Gaussian window and iterative procedure, estimate multiple chirp parameters for multiple spectral peaks.
• Julius O. Smith III (http://www-ccrma.stanford.edu/ jos/Gauss/): Using Gaussian Window, obtain more robust initial chirp parameter estimate. Could be used in iterative procedure as in M+A. (See also comparison of JOS and M+A methods, on http://www-ccrma.stanford.edu/ asmaster/marquesproof/marquesproof/marquesproof.html)
• Master and Liu (ICASSP 2003): Using Hann (NOT Gaussian) window, obtain robust initial chirp parameter estimates. Uses a Fresnel integral analysis.
• Why Hann window instead of Gaussian window? Hann window has more reliable constant-overlap-and-add (COLA) property. Makes the ugly math worth it...
