数字水印技术是近年来图像保护技术研究领域的一个热点, 本文提出了一种基于小波变换的图像数字 水印嵌入算法的Matlab 实现。实验结果表明, 该算法具有较好的视觉效果和透明性。(Digital watermarking technology in recent years is to protect technology research in the field of image a hot, this paper puts forward a method based on wavelet transform is the digital image Watermark imbedding algorithm Matlab. The experimental results show that the algorithm has good visual effects and transparency. )

本程序产生级数为5,6,7的大M序列，并比较其自相关和互相关特性(The program generated series 5,6,7 M sequence, and compare the autocorrelation and cross correlation properties)

在弹载数据链系统中,进行测试验证，实验表 明RS码能够明显改善弹载数据链的误码率性能。(In the onboard data link systems, test validation experiments show that RS code can significantly improve the bit error rate performance onboard data chain.)

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)
