NOISE SUPPRESSION DEVICE Russian patent published in 2006 - IPC H04B1/10 

FIELD: radio communications.

SUBSTANCE: proposed device that can be used in radio communication systems operation under impact of one or more sources of noise differing from signal either by spatial characteristics (whose disposition is not in direction of maximal radiation of antenna directivity pattern) or by spectral characteristics (asymmetry relative to central frequency of signal spectrum) has weighting coefficient shaping unit whereto signals arrive from direction finder that controls direction to noise source and from directivity pattern shape setting unit of antenna-feeder system. Computed weighting coefficients are supplied to adaptive spatial filter which is also supplied with signals from outputs of radio receivers; output signal picked off adaptive spatial filter arrives at noise corrector, noise spectrum being asymmetrical relative to central frequency of signal spectrum.

EFFECT: improved operating characteristics of device due to enhanced signal-to-noise ratio.
