Wiener in frequency domain.
Started by ●April 5, 2005
Hi all.
I am new in DSP, and have a misunderstanding related to Wiener
filtration.
I have both source and desired signals (actually images) available.
As I understand, when Wiener filter is calculated in spatial domain
(straightforwardly or approximated using LMS) with predefined filter
size, it is a FIR filter.
But if it is calculated in frequency domain using H(w)=Pxy(w)/Pxx(w),
is it a IIR filter?
Thanks.
