METHOD FOR DETERMINING STRUCTURE AND DEMODULATION OF SIGNAL WITH UNKNOWN STRUCTURE Russian patent published in 2010 - IPC G06F17/14 G06N3/02 G01R23/16 

FIELD: radio engineering.

SUBSTANCE: invention can be used for purposes of radio control, matched filtering of deliberate interference, hidden determination of characteristics of radio sources and for demodulation of signal with unknown structure. According to invention, identification and demodulation of signal with unknown structure is performed by using two-level signal processing, by means of primary wavelet processing for rough estimation of signal parametres (maximum, minimum amplitude and frequency), presence of phase distortions and for accurate determination of signal parametres of secondary analysis in neuron networks in which there performed is parallel signal processing, and automatic tuning to each type of input signal. At that, accuracy of determining parametres is comparable to noise level.

EFFECT: increasing the accuracy and speed of determining parametres of signal with unknown structure restricted with noise level of input signal.
