1. The automatic identification of the modulation types has been applied to many fields such as source identification , interference identification , radio interception , - electronic countermeasures , etc . the modulation recognizer based on the decision - theoretic approach and the constellation diagram is proposed and the signal ' s kurtosis is used as the indicator to differentiate the analogue modulation from the digital modulation
   通信信号调制类型的自动识别广泛应用于信号确认、干扰辨识、无线电侦听、电子对抗和信号监测等领域。本文提出基于决策论与星座图的综合调制识别器，使用信号的峰度区分调制类型是模拟调制还是数字调制。
