SIGNAL SUPPRESSION FOR SPECTRUM ANALYSIS OF OTHER SIGNAL Russian patent published in 2021 - IPC H04B1/12 G06N3/06 G01R23/167 

FIELD: radio engineering and communications.

SUBSTANCE: disclosed method is intended to suppress the extracted radio-frequency signal for spectrum analysis of at least one other radio-frequency signal. Method includes receiving 602 of mixed signal 108 by analogue-to-digital converter 112. Mixed signal comprises a plurality of separate signals 104a–104n from different signal sources 106a–106n. Mixed signal is digitized by 606 analogue-to-digital converter. Identical first digitized signal 116 and second digitized signal 120 are generated. First digitized signal is delayed by 608 for a given delay time, and the second digitized signal is processed 610 in neuromorphic processor 118 for signal processing to isolate dedicated signal 122. Set delay time corresponds to delay built-in 204 into neuromorphic processor for signals processing. Phase delay and the amplitude of the extracted signal are adjusted 614 based on the phase delay and amplitude of the first digitized signal. Adjusted signal is removed 616 from the first digitized signal to obtain an input analysis signal for analysis 134.

EFFECT: technical result consists in reduction of response time.
