【摘要】：复杂电磁环境下对无线电信号进行监测时,基于时频分析的传统监测方式对频谱混叠信号难以进行识别.针对这一问题,提出了一种电磁频谱管理盲监测技术.在分析研究了盲源分离的理论基础上建立了基于最大信噪比算法的盲监测模型,基于该模型仿真实现了6路频谱混叠无线电信号的分离提取.仿真结果表明:应用所建立的模型能够实现频谱混叠无线电信号的监测分析,判明所监测无线电设备的工作频率、信号形式和带宽等主要特征.
[Abstract]:When monitoring radio signals in complex electromagnetic environment, the traditional monitoring method based on time-frequency analysis is difficult to identify spectrum aliasing signals. To solve this problem, a blind monitoring technique for electromagnetic spectrum management is proposed. Based on the theory of blind source separation, a blind monitoring model based on the maximum signal-to-noise ratio (SNR) algorithm is established. Based on the model, the separation and extraction of six spectrum aliasing radio signals are realized by simulation. The simulation results show that the proposed model can be used to monitor and analyze spectrum aliasing radio signals, and identify the main characteristics of the monitored radio equipment, such as frequency, signal form and bandwidth.
