 03 Sep 2004 16:00 Wiener filter for equlization |

Do you know how to program it ?
I found that Wiener equation in f domain is
W(f) = Pxy(f) / Pyy(f)
where W(f) is Wiener filter response
X(f) is Wiener filter output
Y(f) is input
Is it correct, what do you think?

this one shows the use of wienner filtering in image processing:

As you know matlab provides complete m files, easy to use and ready.
Also this one is interesting:

Also you know that there is a famous book Adaptive Filtering, which is a famous text book in universities, I think that you can easily obtain it and use it's Equations.

oh yeah,
in matlab, it is for image processing
but i try to use it for channel equalization
i wanna know the improvement compare to zero focing EQ
hohohohooo

man,
i found that equalisation is improved if you do it in time domain.
try to derive your filter formula in time domain and tell me what happen.
