摘　　要：信号特征提取是通信调制信号识别的关键问题,文章对数字调制信号进行Gabor变换和Morlet小波变换,然后在变换的基础上用crazyclimber算法提取脊特征,从而基于脊特征达到对通信数字调制信号进行识别的目的。Feature extraction of signals is a key issue in digital modulation signals recognition.After Gabor transformation and Morlet wavelet transformation, by adopting this Crazy Climber Algorithm presented in this paper,the feature of ridge of the communication Signals could be extracted effectively even in low signal-to-noise ratio,which is also shown in simulation experimental results.Based on signal feature extraction,then the different digital modulation signals can be recognised validly.
