Wiener filter is a MMSE estimator. The thing I am concerned about is whether it works in any type of additive noise? Does the expression of WF $H_{wf}(f)={S_{xy}(f)}/{S_{xx}(f)+N(f)}$ fits for...

n(t) is white Gaussian process. T1 and T2 are the periods at which n(t) is sampled, N1=n(m \cdot T1), N2=n(m \cdot T2). S1(f) and S2(f) are the spectrum of N1 and N2 respectively. What is the...
