| 摘 要： | 利用幅度归一化、小波分析、傅里叶变换等方法,在大部分先验信息未知的情况下对 PSK,FSK,QAM,ASK 等不同调制方式的数字通信信号,进行了有效的特征提取,并选取合适的阈值加以识别,实现了数字通信信号调制方式的分类识别。仿真结果表明对于信噪比在5dB 以上的调制信号能正确分类。

| Abstract: | For digital communication signals with different modulation modes such as PSK,FSK,QAM,2ASK,feature extraction is processed effectively and modulation identification is realized by wavelet analysis and several other methods.The result of the simulation shows that signals with R_(SN) above 5 dB can be classified correctly. |

| Keywords: | modulation identification wavelet transform median filter R_(SN) |
