基于DCT算法水印的嵌入和提取MATLAB 程序(wartermark and detecter)

LTI response for a sound file

说明：  这是对于矩阵分解里面，最新出现的一种新的算法：非负矩阵分解的程序(This is the decomposition of the matrix inside, emerging a new algorithm: the procedure of non-negative matrix factorization)

局部均值分解是由Smith提出的一种新的非线性和非平稳信号分析方法。由于LMD是依据信号本身的信息进行自适应分解的，产生的PF分量具有真实的物理意义，由此得到的时频分布能够清晰准确地反映出信号能量在空间各尺度上的分布规律。(Local mean decomposition is a new nonlinear and non-stationary signal analysis method proposed by the Smith. Since LMD information is based adaptive signal itself decomposed, resulting PF component has real physical meaning, when the resultant frequency distribution of the signal can be clearly and accurately reflect the spatial distribution of the energy of each scale.)

可以实现柴油发电机独立带负载运行，负载有常规负载和电动机负载，包含调速器部分和励磁控制部分(The diesel generator can operate independently with load. The load includes conventional load and motor load, including governor part and excitation control part.)

现代通信系统分析与仿真：MATLAB通信工具箱(Modern communication system analysis and simulation: MATLAB Communications Toolbox)

说明：  基于MATLAB的通信系统仿真　bpsk的仿真过程就是这样的 (MATLAB-based communications system simulation BPSK Simulation of the process is)

ESPRIT的谱估计算法，含有自动定阶，设置相应参数即可直接运行。(ESPRIT algorithm for spectral estimation, with automatic set-order, set the corresponding parameters can be directly run.)

matlab文件实现QPSK调制，信号频率1，采样频率100(QPSK Modulation)

说明：  平行射线滤波反投影，算法简单，通过对投影滤波后，重建的图像效果好。(Parallel rays filtered back projection algorithm is simple, by filtering the projection, the reconstruction of the image effects.)
