摘要
现有无线电信号监测方法存在定位精度不准确的问题,为此提出一种通过希尔伯特-黄变换(Hilbert-Huang Transform,HHT)进行无线电信号监测的方法。通过Hilbert变换测量出信号的瞬时振幅、瞬时相频以及瞬时频率,计算出无线电信号各个本征模态分量,获取混合硬盘(Hybrid Hard Disk,HHD)无线电信号,根据实际采集的无线电信号数据计算出监测数据信号的关键参数,最终实时监控无线电信号参量,提高监测的定位精度。通过对比传统的无线电监测方法,使用HHT能够更精确地定位到无线电信号的具体位置,为维护无线电监测结果的权威性、确保其无线电频谱服务的正常合规运营提供理论支持。
The existing radio signal monitoring methods have the problem of inaccurate positioning accuracy,so a method of radio signal monitoring by Hilbert-Huang Transform(HHT)is proposed.Through Hilbert transform,the instantaneous amplitude,instantaneous phase frequency and instantaneous frequency of the signal are measured,the intrinsic mode components of the radio signal are calculated,and the Hybrid Hard Disk(HHD)radio signal is obtained.According to the actual collected radio signal data,the key parameters of the monitoring data signal are calculated.Finally,the radio signal parameters are monitored in real time,and the monitoring positioning accuracy is improved.Compared with traditional radio monitoring methods,HHT can locate the specific location of radio signals more accurately,which provides theoretical support for maintaining the authority of radio monitoring results and ensuring the normal and compliant operation of its radio spectrum services.
