车轮启动时刻的Matlab仿真程序，计算转动和平动速度，和位移。(Moment of the wheel to start Matlab simulation program to calculate rotation speed of the peace movement, and displacement.)

文章对几种常用的基于循环前缀(CP)的最大似然同步算法进行了分析，并对其频偏估计方差进行了比较；同 时针对基于CP 的同步算法在多径衰落信道下性能较差的情况，提出了一种改进的CP 同步算法并进行了仿真，结果表明相比 于原ML 算法，文中算法在多径信道下可有效提高频偏估计性能。(】This paper does some research on multiple maximum-likelihood (ML) algorithms based on cyclic prefix (CP) and compares variances of frequency-offset estimation After the analysis of the bad performance of CP based algorithms in multi-path fading channels, an improved CP algorithm is proposed and the simulation shows that this algorithm can improve its performance effectively in multi-path fading channels.)

本次实验是要我们先产生心电信号，再加噪声再滤波。由一个心电信号数据表输出心电信号，由于已知的心电信号有噪声，所以我先将信号进行滤波，得到正确的心电信号。再加噪声，通过滤波可以得到高频和中频噪声，将原信号加上噪声显示再滤波。每次的时域信号都画出了他们相应的频谱，便于观察。每次的滤波我也尝试了不同的滤波器。(This experiment is to produce our first ECG, together with noise and then filtering. ECG data from a table output ECG, ECG as a known noise signal is filtered first, I get the correct ECG. Plus noise can be obtained by filtering high-frequency and intermediate frequency noise, the original signal plus noise shown again filtering. Time-domain signals each draw their corresponding spectrum, easy to observe. Every time I try to filter the different filters.)

使用拉格朗日松弛最小化方法处理简单的机组组合问题（UC）算例程序，源自电力系统运行与控制一书(Lagrangian relaxation minimization method is used to deal with simple unit combination problem (UC) example program, starts the power system operation and control)

这是关于matlab stateflow的源码例子，其中可以作为入门例子，stateflow经常和simulink一起使用(This is the source code on matlab stateflow examples, examples of which can be used as entry, stateflow often used together and simulink)

计算PSNR。可直接调用，两个输入参数im1,im2为两个图象序列，返回值为PSNR的值。(Calculation of PSNR. Can be called directly, two input parameters im1, im2 two image sequences, the return value is the PSNR.)

lms算法实现滤波，重构权值，对噪声信号进行重构，可以实现时延计算(LMS algorithm filtering, reconstruction of the right value, the noise signal reconstruction, time-delay calculation can be achieved)
