Matlab 图像数字水印 多媒体技术课程设计水印图像的嵌入和提取(Matlab image watermarking multimedia curriculum design watermark embedding and extraction)

说明：  人工小波神经网络的初始化文件，已结合遗传算法，很有特色(A initial souce code for wavelet neural network,which is engaged with GA method)

Blind Source Seperation (BSS) now is a important technology. Independent Component Analysis (ICA) is the main technique of BSS. Suppose we mix many non-Gausse signal sources,ICA can seperate the mixed signal to orignal signals without any information. This Matlab Code simulate the using ICA for Multi User Detection (MUD) in CDMA system. We demo the CDMA system with 30 Users, and use ICA seperate the signal of each user at Base Transmit Station (BTS) with the only 30 Users signal.

多极同步磁阻电机的通用设计，较好的设计方案文件值得您的关注(Multipolar Ferrite-Assisted Synchronous Reluctance Machines A General Design Approach)

说明：  matlab里面使用三倍中误差法消除观测粗差，去除噪声。(matlab error method which uses three times in the elimination of Gross Errors, remove noise.)

These are codes for implementing Bandpass filters in MATLAB. Can be used for study in Digital Signal Processing

说明：  直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)
