修改自pudn的fm_gui_v2.基于相位相关方法（傅里叶变化），可有效实现任意大小两图的位移、尺度变化、旋转量，并输出拼接结果(Modified pudn of fm_gui_v2. Based on phase correlation method (Fourier transform), which can effectively achieve the displacement of any size, the two figures, the scale changes, the amount of rotation, and outputs the result stitching)

窗函数法设计一个数字带通FIR滤波器，小波包分析提取振动信号中的特征频率，PLS部分最小二乘工具箱。( A window function design FIR digital band-pass filter, Wavelet packet analysis to extract vibration signal characteristic frequency, PLS PLS toolbox.)

关于功率谱估计的,周期图法,自相关法,bartlett法和welch法,还有一个复倒谱估计的代码(On the power spectrum estimation, periodogram, since the relevant law, bartlett law and Welch law, there is a Complex Cepstrum estimated code)

这个程序是根据前推回代法计算潮流的，算法简单明了。(This program is based on forward and backward substitution method to calculate the trend of the algorithm is simple and clear.)

说明：  信号处理，误差曲面的优化和误差最小点的寻找(Signal processing, optimization of the error surface and error to find the minimum point)

最小二乘窄带干扰消除。有用信号是一个点状目标，产生窄带干扰采样，产生高斯白噪声，设计一个M=100个系数的单步(D=1)线性预测器，再用得到的线性预测器来消除图中被干扰的信号x(n)中的噪声。(Least Squares narrowband interference cancellation. The useful signal is a target point, narrow-band interference is sampled Gaussian white noise, the design of a M = 100 coefficients in a single step (D = 1) linear predictor, then the obtained linear prediction filter to eliminate the interference graph the signal x (n) the noise.)
