自编图像退化程序，包括图像的模糊与加噪，解释详细，希望对学习图像复原的朋友有所帮助。(Self image degradation process, including blur and add noise, a more detailed explanation, I hope the friends of learning image restoration help.)

sinc插值，可以理解为所有输入样本的加权叠加(sinc interpolation, can be understood as a weighted superposition of all input samples)

这是《Space-Time Codes and MIMO Systems》书中第四章的源程序，包括stbc2x1,2x2,3x1,3x2还有当信道具有相关性时的stbc2x2,4x4等多发多收等的源程序。(This is the "Space-Time Codes and MIMO Systems" source book, Chapter IV, including stbc2x1, 2x2, 3x1, 3x2 as well as when the channel has a relevance stbc2x2, 4x4, etc., etc. overcharged multiple source.)

关于非线性离散系统辨识，调试通过可以使用，各种kalman滤波器的设计。( Nonlinear discrete system identification, Debugging can be used, Various kalman filter design.)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
