I¡¯m investigating how to use diagonal-toeplitz-diagonal factorization to produce good TFR, eg, IEEE paper <<Toeplitz and Hankel kernels for estimating time-varying spectra of discrete-time random processes>>,substitute Eq(31) which is a kernel function into discrete Cohen's class to get Eq(33)which is a TFR.

Wondering if anyone had studied and  like to share experience with me?

there is no integration method, we just use a fast fourier transform.
best regards,

I start to work in time-frquency area and go through some of time-frequency toolbox Matlab functions, and found all the tfrxxx functions are sloved in an flaxible way. Is there anybody could explain which mathmatical linear algebra method is used when you implement the integration equaltion,such as tfrstft,tfrspwv? I'm confused in how to choose the tau range in different tfr equation.

Looking forward to hearing from you soon.
