摘　　要：数字信号调制方式识别技术是盲信号处理的关键技术之一,文中在研究常用的MFSK信号类内识别方法的基础上,研究了一种改进的调制识别方法以克服原识别方法在低信噪比条件下正确识别率较低的不足,改进算法的识别性能在文中进行了仿真实验,实验结果分析可知改进方法可以在低信噪比条件下取得较高识别率,具有一定的实用价值。The modulation classification technique of digital signal is one of the key technologies in the area of blind signal processing. Based on the research of common inter-class modulation classification method of MFSK, an improved method is proposed in order to overcome the disadvantage that the common method＇s accurate discrimination is inferior in the condition of low signal-noise ratio. In this paper the performance of the improved method is simulated. The result of simulation shows that the improved method can gain the high accurate discrimination rate and possess a certain practical value.
