Abstract
In this paper the Wiener estimator for signal-denoising is generalized to
finite frame operators. In particular, a two-stage procedure which results
in a non-linear and non-diagonal estimator is proposed. Advantages and
disadvantages with respect to the classical Wiener estimator used with
orthonormal basis operator are discussed showing results on standard and
real test signals.
