FIELD: radio communications; signal separation in narrow-band noise environment.
SUBSTANCE: proposed method for narrow-band noise correction depends for generating complex Fourier spectrum of time counts obtained as result of output process sampling as well as for shaping complex spectrum of time counts from complex Fourier spectrum which is mirror image of useful-signal wave frequency of time-count complex spectrum followed by shaping sum and difference of these spectrums. Useful signal copy is recovered upon shaping difference spectrum module, its division by two, multiplying by shaped phase multiplicand, and reverse Fourier transform of product obtained.
EFFECT: ability of correcting narrow-band noise under phase-transient channel conditions; enlarged signal frequency band.
