有PMUSIC 校正前和校正后的比较，这个有中文注释，看得明白，可以得到很精确的幅值、频率、相位估计，isodata 迭代自组织的数据分析，使用高阶累积量对MPSK信号进行调制识别，外文资料里面的源代码，预报误差法参数辨识-松弛的思想，详细画出了时域和频域的相关图。- A relatively before correction and after correction PMUSIC, The Chinese have a comment, understand it, You can get a very accurate amplitude, frequency, phase estimation, Isodata iterative self-organizing data analysis, Using high-order cumulants of MPSK signal modulation recognition, Foreign materials inside the source code, Prediction Error Method for Parameter Identification- the idea of relaxation, Correlation diagram shown in detail the time domain and frequency domain.
