摘要
通信对抗中数字通信调制方式识别作为一种非协作通信识别是近年研究的热点,提出一种基于信号瞬时特性并结合决策论对通信信号调制方式进行识别的方法。该方法选用数字通信信号中的五个典型特征参数作为判决准则,然后给出基于决策论判别树的方法,选取恰当的特征门限进行信号识别流程设计。仿真实验结果表明,该方法在信噪比较低时也具有较高的识别正确率和更快的识别速度,更容易工程实现。
Digital communication modulation mode recognition as a non-cooperative communication recognition in commu-nication countermeasure has become a hot spot in recent years.A method of communication signal modulation mode recognition based on instantaneous characteristic and in combination with decision theory is proposed.In this method,the five typical char-acteristic parameters in digital communication signal are selected as decision criteria,and a way based on decision theory dis-crimination tree is given to select appropriate feature thresholds for signal recognition process design.The simulation experiment results show that the method has higher recognition accuracy and faster recognition speed when the SNR is low,and it is easier to realize in engineering.
