说明：  2发1收 与 2发1收的比较 实验次数 2000次，采用LS进行信道估计，ML进行译码，导频符号长度为10 (2 receive and 2 send a send a receive 2,000 times the number of comparative experiments, using LS channel estimation, ML decoding, pilot symbol length of 10)

绘制庞加莱截面图的程序。先通过solveLor.m来求出一系列点，然后代入Poincare_section 程序绘制庞加莱截面。 通过观察Poincare截面上截点的情况可以判断 是否发生混沌：当Poincare截面上有且只有一个不动点或少数离散点时，运动是周期的；当Poincare截面上是一封闭曲线时，运动是准周期的 当Poincare截面上是一些成片的具有分形结构的密集点时，运动便是混沌。 (Poincare section drawing program. First obtained by solveLor.m to a series of points, and then drawn into the program Poincare Poincare section. By observing the situation on the Poincare section cut points can determine whether chaos occurs: When there is only one fixed point or a few discrete points on the Poincare section, the motion is periodic When is a closed curve on the Poincare section, the motion is quasi- When is the point of having a dense fractal structure on some stretches of the Poincare section, the motion is chaotic period.)

这是一个虹膜识别码。它会要求用户将图像保存到数据库中。保存到数据库后，您可以将其与存储在数据库中的另一个图像进行比较。这是识别人眼虹膜的最佳代码

利用C、C＋＋或者MATLAB对一张照片进行DCT和DFT变换，并进行简要分析。 比较保留20个DCT变换系数重构的图像与原始图像之间的差别(Use C, C++ or MATLAB to carry out a photo on the DCT and the DFT transform, and a brief analysis. Comparison of retention of 20 DCT transform coefficients of image reconstruction with the difference between the original image)
