WebFeb 5, 2024 · Specification of length L FIR filter coefficients of a Wiener deconvolver seeking to estimate x [ k] from y [ k] is straight-forward for stationary noise. Things are more complicated for non-stationary noise. Strictly speaking non-stationary noise requires a different filter for every sample instant k which is prohibitively complex.

Weboptimum filter. The Wiener filter is probably the most common definition in use, and it relates to the configuration depicted in Figure 7.2. The kth sample of signal y, y k, consists of two components: the principal signal sk, and a noise component nk which is correlated with xk. The Wiener filter provides an optimal estimate of nk, known as nˆ k.

Although by the 1970s the FIR form of the Wiener filter was already known, much work was then carried out in finding the solution to the more general IIR problem. At the same some authors looked at the case of multivariable solutions. This chapter looks at the polynomial solutions to the Wiener filter, smoother and predictor.
