Matlab--QPSK

汽车爬坡度计算，m文件。用matlab软件打开。(Vehicle gradient calculation, m file.)

说明：  超好的crc编码 与解码 在matlab中实现(Super good crc encoding and decoding is implemented in matlab)

对文件夹中的文件自动编号或恢复为旧文件名。当然，经过小的修改，也可完成其他批量修改文件名的功能，如批量修改后缀名等等。利用MATLAB的GUI技术，做了个界面，方便用户使用(Automatic numbering files in the folder or revert to the old file name. Of course, after minor modifications, to be completed by the functions of the other batch change file names, such as batch modify the extension. MATLAB GUI technology, made the interface, user-friendly)

说明：  本程序运行需一个小时左右。优化准则是旁瓣电平最小。取栅格间距为lemda/2,阵元间距为栅格间距的整数倍。放阵元的位置放1，否则放0(This program should be running an hour or so. Rule of optimization is side-lobe level minimum. Take grid spacing for lemda/2, spacing for grid spacing array (integer times. Put the position of the array (put 1, otherwise put 0 )

本模块对车用动力锂电池的三种主要等效电路模型进行建模和仿真，搭建了相应的仿真模块。(In this module, three main equivalent circuit models of vehicle power lithium battery are modeled and simulated, and the corresponding simulation module is built.)

一篇文章，介绍如何在MATLAB/SIMULINK中实现可视化动画仿真，实用性很强(An article describes how MATLAB/SIMULINK simulation to achieve visual animation, very practical)

说明：  检测两个输入信号的相位差。DFT_main函数中模拟了三种曲线，并对比了计算出的相位与理论相位的误差。(Detect the phase difference between two input signals. Three kinds of curves are simulated in DFT main function, and the errors between calculated phase and theoretical phase are compared.)

说明：  基于MATLAB平台的微分进化策略的实现(The realization of differential evolution strategy based on MATLAB)
