水印抗攻击：由高斯正态分布序列 g1 产生 36×4 的水印信号 w0，w0 由(0,1)组成。(Watermark against attacks: from the Gaussian normal distribution generate 36 × 4 series g1 watermark signal w0, w0 from (0,1) component.)

fft谐波检测，分析信号的频谱和幅值，相位(fft harmonic detection, analysis of the signal spectrum and amplitude, phase)

在matlab环境下对DV-HOP算法的实现，可以直接运行(DV-HOP algorithm implementation)

通过matlab代码，小波包分析提取振动信号中的特征频率，可以得到很精确的幅值、频率、相位估计。( By matlab code, Wavelet packet analysis to extract vibration signal characteristic frequency, You can get a very accurate amplitude, frequency, phase estimation.)

用于将长的信号break into小的piece，然后对每段小piece做信号处理，然后再将整个的信号还原回原始信号长度。(The signal is used to break into long small piece, and then each small piece to do signal processing, and then restore the signal back to the original signal length.)
