Research and Implementation of Spectrum Monitoring Method for Terrestrial Digital TV Signal
In order to monitor the legitimacy of the spectrum of radio and television signals,this paper designs the construction method of the spectrum integration diagram and spectrum line integration diagram.At the same time,it designs the spectrum shape data analysis method and spectrum matching method and solves the problems of spectrum recognition greatly affected by noise,a large amount of spectrum monitoring calculation,and high cost in the existing technology by using the spectrum matcher with signal acquisition module,signal processing module,and data storage module.The results show that it can search,identify,and audit illegal channels quickly,reliably,and robustly.
