Synthesis of economical noise-suppression filters
Abstract
Filters that are optimal according to the criterion of minimum output power are constructed for the suppression of noise with Toeplitz correlation matrices. Also imposed is the minimum-rms-error criterion, where constraints are placed on the first or last weight coefficient. It is shown that, from the computational point of view, the synthesized filters are considerably more simple than previously existing filters.
