WebNov 19, 2024 · Abstract. 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.

In signal processing, the Wiener filter is a filter used to produce an estimate of a desired or target random process by linear time-invariant (LTI) filtering of an observed noisy process, assuming known stationary signal and noise spectra, and additive noise. The Wiener filter minimizes the mean square … See more The goal of the Wiener filter is to compute a statistical estimate of an unknown signal using a related signal as an input and filtering that known signal to produce the estimate as an output. For example, the known signal might … See more 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 … See more The filter was proposed by Norbert Wiener during the 1940s and published in 1949.

However, a causal filter with FIR structure is often preferable [83]. Although an IIR filter can be subjected to truncation, the resulting FIR filter no longer has an obvious relation to the MMSE. WebJul 27, 2024 · Technically, there are a lot of different “Wiener filters” too, and I’m deliberately simplifying things. The Kalman filter converges to the discrete-time IIR Wiener filter, which is to say, the best kind of Wiener filter. :) There are also FIR Wiener filters, which are perhaps more commonly encountered.
