Re: [Tftb-help] pls help

Hi,
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?

thanks,
Jocelyn
