摘　　要：为了对广播电视信号的频谱合法性进行监测,本文设计了频谱积分图及频谱线积分图的构建方法。同时设计了频谱形状数据分析方法和频谱匹配方法,通过利用带有信号采集模块、信号处理模块、数据存储模块的频谱匹配器解决了现有技术中频谱识别受噪声影响大、频谱监测计算量大、成本高的问题。结果表明可以快速、可靠且鲁棒性好地搜索、识别、审核非法频道。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.
