| 摘 要： | 文章介绍了一种新的MPSK信号识别方法，该方法基于信号星座图旋转和同相分量的四阶累积量，通过傅立叶级数展开提取了一组特征向量送入神经网络分类器进行分类识别。仿真结果表明该方法识别正确率高、信噪比要求低。

| Abstract: | This paper introduces a new method to identify MPSK signals.It is based on constellation rotation of the signal and a 4th order cumulant of its in-phase component. Using Fourier series expansion, we extract a group of features which are then used in a neural classifier. The result of the experiment shows that this method has high successful recognition rate,low demand of signal-to- noise ratio. |
