周期图法功率谱估计，希望对大家能有所帮助。(Periodogram Power Spectral Estimation)

求peaks函数的极值。中间有一步需手动选取6个点。(get extream values of peaks function. You need to pick six points in one step.)

归一化自适应算法，是正弦信号的不是语音信号的！欢迎下载使用！(Normalized adaptive algorithm, is not sinusoidal signal of speech signals! Welcome to download! )

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)

说明：  这是很有用的模式分类原代码，值得借鉴！推荐下载！(This is a very useful pattern classification original code, is worth learning! Recommended download!)

新开发出来的经验模态小波变换工具及其例程。(EWT toolbox.)

this is code fore lms noice

说明：  使用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using the FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)

波阈值去噪，比较了软阈值，硬阈值及当今各种阈值计算方法和阈值函数处理方法的性能，通过信噪比及均方差的比较，得出各种的算法的优劣(Wave threshold denoising compared soft threshold and hard threshold and the current calculation method and the various thresholds threshold function processing performance of the method by SNR and mean square deviation of the comparison, the pros and cons of various algorithms)
