摘要
在对不同调制信号谱相关函数及其三组特征谱平面图分析的基础上,提出几种可用于调制信号自动识别的谱相关特征参数,并讨论了对其识别的方法与流程。仿真表明,该方法在低信噪比下识别效果良好。
Based on analysis of the spectral correlation function and three characteristic spectral planes of different modulated signals, several available characteristics are presented in this paper for identifying automatically modulated signals, which is followed by an identification method and its procedure. The results clarify its effectiveness even when signals are buried by noise.
