LPC using cumulants

Started by shamailsaeed July 4, 2008
Hi All,
I want to implement LPC using cumulants (instead of LPC using
autocorrelation ) algorithms in C.
Where can I find that algorithms.
some formulas or c code.

The LPC coefficients follow from the Yule-Walker set of equations (or normal equations). You would need a similar expression for cumulants- does such a thing exist? K.
