自适应外差滤波器matlab代码：采用调制技术，控制正余弦信号对准干扰的频率，将输入的干扰搬移到的低频进行滤波，滤波处理后的信号再经过一次调制搬移到原来的频率位置，这样我们就得到了合适的干扰复制信号，再将输入信号和干扰复制信号进行差分运算达到抑制干扰的目的(Adaptive heterodyne filter matlab code)

本段代码实现了手动选点的matlab配准，在此代码中只选择了3对控制点，同时从结果可以看出手动选点配准的不精确性，为自动选点配准算法的提出提供了实验依据(This code implements manually selected point matlab registration, in this code to select only the three pairs of control points, and the results can be seen from the point of registration manually selected imprecision, with the choice of site for the proposed automatic registration algorithm provide an experimental basis)

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)
