本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。(This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantization DCT coefficients and then use the parity properties of 8-bit grayscale watermark embedding map, and through the PN sequence of encryption to ensure the security of the watermark. Algorithm, the gray image into binary data stream, scrambling after the spread spectrum modulation, hidden in the host DCT coefficient quantization values, the extraction does not require the host signal, the blind watermark extraction.)

该文件是间接式双级矩阵变换器的开环仿真模型。输出结果符合理论推导。采用s函数编程的方法实现空间矢量调制策略(This file is indirect two-stage matrix converter of the open loop simulation model. Output the results accord with theoretical derivation. The s function programming method of space vector modulation strategy. )

基于聚类分析的蚁群算法，主要是应用于多目标选址问题(Ant colony algorithm based on cluster analysis is mainly used in multi-objective location problem)

A few examples of designing and implementing fir filters with Matlab-filtering a signal taken from the mic input of the soundcard and putting it on the headphones output chanel and removing noise from ECG.I m uploading this file just because I need to register to see another file and I haven t translated it in English but the code is understandable. If someone is interested e-mail me.
