METHOD TO DETECT RADIO SIGNALS Russian patent published in 2012 - IPC G06K9/00 H04L27/00 

FIELD: information technologies.

SUBSTANCE: previously from digitised and quantised counts of reference RS, matrices of energy distribution are generated on the basis of their frame wavelet transformations. From them vectors of criteria are generated by means of line-by-line concatenation of all wavelet coefficients. Afterwards elements of criteria vectors are normalised and ranged. Each RS received for identification is broken into N fragments, for every of which vectors of criteria are formed in a similar manner. And as vectors of criteria of an RS received for identification, averaged values are selected for normalised and ranged vectors of criteria vectors of all N fragments. A decision on inclusion of a received RS to one of references of recognised classes is taken by results of comparison of its criteria vector with vectors of reference criteria.

EFFECT: higher probability of proper recognition due to reduction of influence of a primary signal determined with an information component at generated vectors of criteria.
