As I know, there is a good paper talking about this, B. R. Bennett, 'Spectra of Quantized Signal' 1948.
I am wondering there is newer report on this topic for the signal with colored spectrum? Thanks,
Does any IEEE journals accept the circuits (Antenna/RF/Basedband/SOC) articles which is based on simulations only(e.g. ADS, LabVIEW...)?

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...
