METHOD FOR AUTOMATIC DETECTION OF NARROW-BAND SIGNALS Russian patent published in 2010 - IPC H04B1/10 

Abstract RU 2382495 C1

FIELD: physics; radio.

SUBSTANCE: invention relates to radio engineering and specifically to methods of detecting narrow-band signals in expected uncertainty conditions and can be used in radio communication lines working under effects of additive noise. The method for automatic detection of narrow-band signals involves the following sequence of steps: an analogue signal is received and converted to digital, noise power ratio is then calculated and ratio of spectral components which are, respectively, greater and not greater than the noise power ratio is calculated and then compared with a pre-calculated threshold value.

EFFECT: wider range of use for an arbitrary class of narrow-band radio signals in additive noise without prior knowledge of values of their characteristics and noise parametres.
