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.
