Yes, I see....the signal with compact support can have zeros outside of ROC...
Btw, what does "ROC" mean?
- unwrap phase; take result of (2) as phase and magnitude
- multiply (FT of weights) by mag^alpha*( cos (phase*alpha) + i
sin(phase*alpha) )
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"?
Maybe there's an eigenvalue/vector trick that I'm missing...
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 ;-)
