METHOD FOR RECOGNIZING RADIO SIGNALS Russian patent published in 2017 - IPC G06K9/00 G06F17/10 

FIELD: radio engineering, communication.

SUBSTANCE: method for recognizing radio emissions, which consists in the fact that the signal information part is selected to form the recognition features of the radio signals by the structural and temporary construction. The selected signal part is digitized and processed. Then the number of the most informative approximation coefficients is estimated for the continuous wavelet transformation, the signal vector is formed based on the number of the most informative coefficients. The integral indicator is calculated by using the energy characteristic indicators of the signal and the wavelets. The wavelet function, providing the maximum contrast of the radio signal feature - scalograms, is selected by the maximum value of the integral indicator. The signal scalogram is constructed by the continuous wavelet transformation, which is taken as the recognition feature.

EFFECT: enhancing the contrast of the radio recognition features.
