FIELD: physics.
SUBSTANCE: invention relates to noise attenuation in signal. Noise attenuation device comprises receiver for receiving first signal of environment, which contains component of required signal corresponding to signal of required source of environment, and component of noise signal corresponding to noise in environment, two code books, input for receiving sensor signal, which is measurement of environment, segmentator for segmentation of first signal into time segments, noise attenuator, configured to perform for each time segment stages of forming of plurality of estimated versions of signal and noise attenuation of first signal in given time segment in response to version of signal.
EFFECT: improved more accurate noise attenuation and simplification of noise attenuation.
