说明：  matlab教程,里面有许多有用的方法.(matlab tutorial, there are many useful ways.)

EMD工具箱，网上很多EMD工具箱有误或者混乱，本EMD工具箱添加到MATLAB的toolbox即可用。(The EMD Toolbox, a lot EMD toolbox wrong or confusing, this EMD toolbox add to the MATLAB toolbox you can use.)

一本工具书，详细介绍了simulink的各个模块。(A book, detailing each module in Simulink.)

语音信号的分帧处理，实现语音的非平稳化为准平稳过程，利用一些平稳信号的处理方法来处理语音信号。(The sub-frame of the speech signal processing, non-smooth voice of whichever stationary process, some stationary signal processing methods to process voice signals.)

说明：  提取opencart产品名称里的属性信息到目录属性里，实现opencart的目录筛选功能。具体属性需添加到文件内，具体看文件说明。(Extraction of Opencart product name in the attribute information to the directory attributes, implementation of Opencart directory screening function. The specific attributes need to add to a file, see the specific documentation. )

说明：  基于互质采样-分段相参积累多项式相位变换的微弱线性调频信号检测算法。该代码的相关论文以oral presentation的形式发表于2018年10月在南京举行的IET国际雷达会议。(Multi-component LFM parameter estimation via order-2 DPT (overlapping and coprime) Author: Dr. Shengheng LIU)

先将47168bit的宿主音频等步长分段,分为1000段，然后混沌序列选择其中的102段，对每段进行3及小波分解，挑选出绝对值最大的系数，运用嵌入公式。(47168bit first step of the host audio sub-divided into section 1000, and then select one of the 102 chaotic sequence segment, on each piece of a 3 and wavelet decomposition, the largest absolute value coefficients selected using the embedded formula.)

用小波去噪，不同尺度下的阀值去噪，去噪效果的对比很不错(Using wavelet denoising, different scales of threshold denoising, contrast denoising effect is very good)

用于对信号的HHT分析，可得到IMF、功率谱、边际谱等图(HHT for signal analysis, obtained IMF, power spectrum, marginal spectrum, etc. Figure)

matlab三相四线制的仿真模型，通过实验据对可靠使用，很好的资料(three-phase four-wire system matlab simulation model using experimental According to a reliable, good information)
