WebA typical communication system design involves first passing the signal to be trans-mitted through a whitening filter to reduce redundancy or correlation and then trans-mitting the resultant whitened signal. At the receiver, the recorded signal is passed through the inverse whitening filter and the original signal is thus restored. However, WebOct 22, 1994 · It is emphasized that computation of an inner matrix corresponds to performing a spectral factorization and the inverse of the outer matrix is a whitening filter.

WebIn principle, the inverse filter provides an exact solution to the problem when the noise term n ij can be neglected. However, in practice, this solution is fraught with difficulties. First, the inverse filter is invariably a singular function. Equally bad is the fact that, even if the inverse filter is not singular, it is usually ill-conditioned.
