基于谱特征的数字信号调制方式识别

摘要

A ccording to the theory of spectral correlation and the analysis of spectral correlation function and feature plane figures of common digital signals, some characteristic parameters to be used in modulation recognition are proposed and the method as well as process of applying the parameters to modulation recognition are discussed. The simulation shows that the method presents great recognition results.%根据谱相关函数理论和对常见的数字信号的谱相关函数及特征平面图分析，提出了几种可用于调制方式识别的特征参数，讨论了利用这些特征参数进行调制识别的方法和过程。仿真表明，这种方法有很好的识别效果。
