smoothing and prediction problems in a unified framework.In order to compute the optimal weighting matrices,the formula of computing the cross-covariance matrices among local filtering errors,is presented.Compared with the single sensor case,the estimation accuracy is improved.A simulation example for a...
They presented an example in which the Wiener–Levinson algorithm produced a prediction filter exhibiting significant error. In recent years there has been controversy in mathematical literature relating to stability of algorithms, such as the Wiener–Levinson algorithm, for solving linear systems of ...

and others are far more complex. In the case of the empirical Wiener filter [4], no explicit statistical model is used at all. Rather, a pilot or prototype estimate is used in lieu of a parametric statistical model. While all of these methods may go by the name of ‘Wiener filter’,...

A similar approach has been proposed in [20], where the Wiener filter has been used as a post-processor to denoise the contaminated ICs. In opposition to [20], our technique uses a multichannel counterpart of the Wiener filter and does not require the ICA. The proposed method relies on ...
