这是关于数字水印的攻击例程！经过调试，可以放心使用！(This is on digital watermarking attacks routines! After debugging, can be assured use!)

两种LFM脉冲压缩技术，第一种技术广泛用于窄带和中等宽带的雷达工作(The two LFM pulse compression technology, a technology widely used in narrowband and medium-wideband radar)

可以用来进行全相位FFT的频谱分析，对比FFT和全相位FFT(Can be used to carry out all phase FFT spectrum analysis of, contrast FFT and the all phase FFT)

在一定的约束条件下，其输出与一给定函数（通常称为期望输出）的差的平方达到最小，通过数学运算最终可变为一个托布利兹方程的求解问题。维纳滤波器又被称为最小二乘滤波器或最小平方滤波器，目前是基本的滤波方法之一。维纳滤波是利用平稳随机过程的相关特性和频谱特性对混有噪声的信号进行滤波的方法，1942年美国科学家N.维纳为解决对空射击的控制问题所建立，是40年代在线性滤波理论方面所取得的最重要的成果。(Under some constraint conditions, the output with a given function (often referred to as expected output) the square of the difference between the minimum, through mathematical operation can be turned into a final taub Leeds equation to solve the problem.Wiener filter is also known as least squares filter or least square filter, is now one of the basic filter method.Wiener filtering is to use the related characteristics of stationary random process and spectrum characteristics of mixed with noise signal filtering method, scientists in the United States in 1942 n. wiener established to solve the control problem of empty shooting, is 40 s in the theory of linear filtering is the most important results.)

FFT算法C语言实现 和MATLAB中fft函数结果一样的功能(FFT algorithm C language and MATLAB fft function results in the same function)

该编码可以成功的实现dpsk的差分编码，直接可以成功的运行，作为其他程序的子程序。稍作修改还可以应用到8psk上(err)

决策树算法的CART算法，用MATLAB编写，能有，不错的。(CART decision tree algorithm algorithm, using MATLAB to prepare, to have, good.)

三维的分数阶傅立叶变换，用于非平稳信号处理(the 3D Fractional Fourier Transform)
