WebIn order to compute the filter coefficients of an Mth-order filter, the Levinson–Durbin algorithm requires the computation of all filters of order less than M. Furthermore, during … Webfilters studied in this chapter are linear optimum discrete-time filters, which include discrete Wiener filters and discrete Kalman filters. All of the topics in (linear) optimum filtering can be developed based on a single fact known as the orthogonality principle, which is the consequence of applying the optimization theory.

The causal finite impulse response (FIR) Wiener filter, instead of using some given data matrix X and output vector Y, finds optimal tap weights by using the statistics of the input and output signals. It populates the input matrix X with estimates of the auto-correlation of the input signal (T) and populates the output vector Y with estimates of the cross-correlation between the output and input …
