In order to improve the filtering ability of spatial interference harmonic noise in digital electronic circuit,an automatic suppression method of spatial interference harmonic noise in digital electronic circuit based on matched filter detection is proposed.The spatial signal transmission model in digital electronic circuit is constructed,and spatial spectrum beamforming method is adopted to conduct adaptive focusing processing of spatial interference harmonic signals of digital electronic circuits,and to extract relevant power spectrum characteristic quantities of interference signals,and the adaptive equalization noise reduction method is used to separate the noise from the interference signal.The filtering model of spatial interference noise signal in digital electronic circuit is constructed.The matched filter detector is used to filter and detect the spatial interference signal in digital electronic circuit,and the automatic suppression of spatial interference noise in digital electronic circuit is realized.The simulation results show that the output signal-to-noise ratio(SNR)of spatial interference suppression in digital electronic circuits is high,and the filtering performance of signals is better,which improves the accurate transmission and detection performance of signals in digital electronic circuits.
