High Precision Automatic Monitoring System for Track Communication Signals under Various Interference
The category identification of track communication signal is not accurate because of the poor effect of interference fil-tering.Therefore,a high-precision automatic monitoring system for track communication signal under various interference con-ditions is studied.The system uses AT89C52 single chip microcomputer as the central processor,and separately filters the sig-nal processing electromagnetic interference and co-frequency interference through digital filter and complex filter.The track communication signal is transmitted to FPGA after filtering,the signal features are extracted,and the dynamic parameter iden-tification model of track communication signal is constructed by combining the feature decomposition method,so as to identify the category of track communication signal with high precision and realize the high-precision automatic monitoring of track com-munication signal.
