dct变换+扩频的数字水印算法 水印为随即序列(Extra transform Spread Spectrum Watermarking digital watermarking algorithm for the forthcoming series)

多进制LDPC码的高斯消去方法的matlab源代码(Binary LDPC codes Gaussian elimination method matlab source code)

说明：  这段程序用于实现封闭空间逃生模拟，通过这段程序可以看到在一个封闭空间中，很多人是如何高效逃生的。(This program used to implement analog to escape an enclosed space, you can see through this process in a closed space, a lot of people how to effectively escape.)

closed loop control of inverter

直接序列扩频DSSS， 跳频扩频FHSS， 码分多址CDMA编译码， 的实现(the realization of Direct Sequence Spread Spectrum DSSS, frequency hopping spread spectrum FHSS, Code Division Multiple Access CDMA codec, )

Two functions for projection matrix estimation (the two methods can be found in Trucco).

说明：  这是一个用带亮度傅立叶描述子提取纹理特征的程序(This is a band brightness using Fourier descriptors of texture feature extraction procedures)

基于<<Discrete Fractional Fourier Transform Based on Orthogonal Projections》的分数阶傅立叶变换(Fractional fourier transform based on 《Discrete Fractional Fourier Transform Based on Orthogonal Projections》)

基于MATLAB的程序编码。实现一种编码方式，实现对信号的内插级抽取(MATLAB-based program code. Implement a coding scheme to achieve the interpolation level signal extraction)

再matlab上实现基于扩频的数字水印。图像处理(This is a simple spread-spectrum based informed watermarking implementation in MATLAB. )
