为提高MPSK信号的类内识别率，分析了MPSK信号正弦类Haar小波变换信号的相位信息，通过提取脊线拟合函数相位的方法对MPSK信号进行类内识别。对提出的方法进行了数值分析和仿真实验，得到8PSK信号的相位提取图，并对不同MPSK信号在无噪和有噪两种情况下进行识别分析，最后得到调制方式识别率曲线。分析和实验结果表明，提出的识别方法正确识别率在90%以上，并且具有一定的抵抗通信干扰能力。

The phase information of the sinusoidal Haar wavelet transform of MPSK signals is analyzed to improve the within?class recognition rate of MPSK signals. The within?class recognition of MPSK signals is achieved by means of extracting the fit?ting function phases of regression line. The mathematical analysis and simulation experiments were performed for the proposed phase extracting method. The phase extracting diagram of an 8PSK signal was derived,the recognition analysis for different MPSK signals under two situations of both non?noise and noise was conducted,and then the recognition rate curves of the de?rived modulation mode were obtained. The analysis and simulation results show that the recognition rate of the proposed method is above 90%,and the method has a certain capability of anti?jamming.
