通过在语音信号中嵌入鲁棒性水印和脆弱性水印，实现对数据的版权保护。(Embedded in the speech signal through robust watermarking and fragile watermarking, copyright protection to achieve the data.)

This project deals with modeling and simulation technique of a Dynamic Voltage Restore (DVR).The DVR is a dynamic solution for protection of critical loads from voltage sags / swells. The DVR restores constant load voltage and voltage wave form by injecting an appropriate voltage. Present novel structure improves power quality by compensating voltage sag and voltage swells. The transient response of any natural system is the way in which the response of the system behaves as a function of time. Electromagnetic transient studies have always played an essential behavior of the system in the event of different forms of transient phenomena, which can hardly be achieved by other means. This project addresses the transient studies of electrical networks with embedded, power electronics-based, FACTS and Custom Power (CP) controllers.

matlab code for HERRORBAR

kalman filter 的入门程序 包括 m 文件和 simulink 仿真文件 对于初学者 入门是很好的资料 (both m files and simulink models are included, which will be very helpful, especially for newlearners. )

说明：  画麦克风阵列的极坐标图，需要输入角度范围，增益，增益范围等参数(painting microphone array of polar map, the need to import perspective, gain and range parameters)

This package implements fast compressed sensing using structurally random matrices (SRM) described in [1] and [2]. As the package is still under development any comments or bug reports are highly welcome.

ofdm的matlab实现，包括bpsk fft(ofdm of matlab realization ,inlude bpsk fft)

相关分析法实例，自己做的不错的东西，相信有同学会用的到 (Instances of correlation analysis, its good to do something, I believe will be useful to students)

说明：  拉普拉斯高斯算子 拉普拉斯—高斯算子（Laplacian of Gaussian算子，通常缩写为log算子）是一种二阶微分算子，将在边缘处产生一个陡峭的零交叉。(Laplace Gaussian operator Laplace- Gaussian operator (Laplacian of Gaussian operator, often abbreviated as log operator) is a second-order differential operator, will be generated at the edge of a steep zero crossing.)

elasticsearch-river-mongodb 源码,主要讲述elasticsearch 和 mongodb 同步索引实现。可以实现自己编译。(Elasticsearch-river-mongodb source code, including elasticsearch and mongodb synchronization index. Can be compiled.)
