说明：  本部分根据RS编译码原理，建立了SIMULINK仿真模型，可以对个参数不同设置，分析各参数对RS码性能的影响。(in this part we have build the mode of RS by simulink.we can analyze the impose of any keys to the function)

计算功率谱（或互谱）的matlab子程序(Calculate the power spectrum)

GCC-PHAT algorithm to calculate the maximum TDOA

RGB彩色空间转换至HSI彩色空间,带注释.(RGB color space conversion to HSI color space, with Notes.)

Neighborhood rough set based feature evaluation and reduction

说明：  用matlab实现的GSM TCH/FS系统在高斯信道、瑞利信道的性能仿真，其中用到了循环编码、卷积码、交织码等信道编码知识(Using matlab to achieve GSM TCH/FS system in the Gaussian channel, Rayleigh channel performance simulation, which uses a loop encoding, convolutional codes, interleaving codes channel coding knowledge)

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.)
