RADIO SIGNALS MANIPULATION TYPES RECOGNITION METHOD Russian patent published in 2019 - IPC G06N3/02 

FIELD: physics.

SUBSTANCE: invention relates to the field of the radio signals processing and recognition, in particular to the radio signals manipulation type recognition, and can be used in the radio devices for the radio signals manipulation recognition. Radio signals manipulation types recognition method differs in that by the signal N counts in-phase and quadrature component values eliminating its detuning by the carrier frequency by the de-tuning correction introduction, to which to the cumulant C₄₀ module maximum value is corresponding, calculating the cumulants C₄₂ and C₆₁ values, and submit them to the previously trained by the cumulants C₄₂ and C₆₁ training sample signals values backpropagation error the multilayer perceptron type neural network, which recognizes the signals.

EFFECT: automatic recognition of the radio signal manipulation types in the absence of high-precision synchronization with the input signal carrier frequency for the of manipulation types wide alphabet (4-level pulse amplitude manipulation, binary phase, quadrature phase, the 8^th order phase manipulation, the 8^th, 16^th and 32^nd order quadrature manipulation).
