Simulink仿真的详细介绍，并且有图像说明。让您更好的掌握方针方法(Simulink)

说明：  自己用simulink搭建的FSK相干解调模型（有误码率分析）欢迎改进和交流 (Own use to build the FSK coherent demodulation simulink model (with bit-error rate analysis) welcomed the improvement and the exchange of)

离散傅里叶变换的子程序，matlab的built in函数的一部分程序(Discrete Fourier Transform subroutine built in matlab function part of the program)

粗糙集属性约简相关论文，感觉不错，用来分享一下(Rough set attribute reduction related papers, I feel good, to share)

一种基于最小熵反褶积( ]8+83)3 6+D*(A4 Q20(+W(-)D8(+，]6Q) 的滚动轴承故障特征提取方法: 在利用 /X 模型去除齿轮啮合产生的确定性信号的基础上，对保留信号进行最小熵反褶积，增强冲击信号"该方法避免了传统轴承故障诊断方法中带通滤波器设计的难题，实车测试表明: 与共振解调技术相比，该方法提取的滚动轴承故障特征更加明显，更适合于工程应用"(Based on minimum entropy deconvolution (] 8+83) 3 6+D* (A4 Q20 (+W (-) D8 (+,] 6Q)' s fault feature extraction method: using/X model to remove the uncertainty generated signal gear on the basis of the retention signal minimum entropy deconvolution, and enhance the impact of signal " This method avoids the problems of traditional bearing fault diagnosis method of the bandpass filter design, real vehicle test showed that: compared with the resonance demodulation technology, which fault feature extraction method is more obvious, more suitable for engineering applications. " )

说明：  轴承故障信号vmd分解及输出频谱图和幅值图，内含main、vmd及输出频谱图和幅值图三个程序，直接用main就行(VMD decomposition of bearing fault signal and output spectrum and amplitude diagram)
