多缝弗朗和费衍射，改变缝宽和光栅常数来改变光强(Multi-slit Fraunhofer diffraction grating constant change to change the slit width and intensity)

说明：  MATALAB编写的QPSK用于载波同步的锁相环，其结构为平方环(MATALAB编写的QPSK的用于载波同步的锁相环，其结构为平方环)

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)

程序分形分析工具箱 - FracLab2.04MATLAB包括拥有数百个内部函数的主包和三十几种工具包。工具包又可以分为功能性工具包和学科工具包。功能工具包用来扩充MATLAB的符号计算，可视化建模仿真，文字处理及实时控制等功能。学科工具包是专业性比较强的工具包，控制工具包，信号处理工具包，通信工具包等都属于此类。(Program fractal analysis toolbox- FracLab2.04MATLAB including internal functions with hundreds of primary packages and several 30 kits. Kits can be divided into functional disciplines toolkit and toolkit. Function tool kit used to expand the MATLAB symbolic computation, visualization, modeling and simulation, word processing, and real-time control functions. Discipline tool kit is relatively strong professional toolkit, Control Toolkit, signal processing toolkit, communications toolkit belong to this category.)

You all might have used CTime or CTimeSpan to manipulate the system timer. Here is an article to show you how your system timer works. I will give you an idea of port communications behind the system clock manipulations. Those who are a little biased on hardware and software interfacing practices would find this article of great help.
