中文说明：matlab程序运行时导入数据文件作为输入参数，使用高阶累积量对MPSK信号进行调制识别，是学习PCA特征提取的很好的学习资料，是国外的成品模型，有循环检测，周期性检测，分析了该信号的时域、频域、倒谱，循环谱等。
English Description：
Matlab program is running into data files as input parameters, using high order cumulants for modulation recognition of MPSK signals, is learning PCA feature extraction of good learning materials is the refined model of foreign, cycle detection, periodic testing, analyzes the the signal of time domain and frequency domain, cepstrum, cyclic spectrum.
