| Abstract: | 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. |
