Btw, what does "ROC" mean?

That causes the signal's complex cepstrum to be multiplied by alpha? why
do you do it, and why do you consider alpha as an "adaptation
coefficient"?

Don't eigenvalue methods only work on linear transforms? Where's your
linear transform? (Fourier transforms are linear, but I haven't seen
anyone eigendecomposing Fouriers yet...)
sorry for the "newbie" questions ;-)
