matlab在通信原理中的应用，信道编码循环码仿真，希望大家能用得上！(matlab in Communication Theory in the application of channel coding cycle simulation code, I hope everyone can useful!)

本程序使用matlab编码，能实现对运动目标的检测，适合初学者学习(This procedure using matlab coding, to achieve the detection of moving targets, suitable for beginners to learn)

我编写的两相机定标算法，利用matlab toolbox得到初始数据进行一步的标定和优化，其中调用了matlab toolbox里的显示函数和(I prepared two camera calibration algorithm, using matlab toolbox to obtain the initial data calibration and optimization step, which is called the matlab toolbox in the display functions and)

说明：  处理带约束的多目标粒子群算法，十分的好用，通用性很广(Handling constrained multi-objective particle swarm optimization)

用传输矩阵的方法来计算光子晶体带隙，matlab文件(Transfer matrix method used to calculate the photonic crystal band gap, matlab file)

这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波的OFDM，运行此程序需2分钟－3分钟的时间。 (This is a very good CP for OFDM-based maximum likelihood symbol timing synchronization and carrier synchronization of the MATLAB simulation program, after I read the absorption of classical literature in depth, repeated programming and debugging derived, code refining orderly, absolute no mistake, this process has been synchronized simulation curve is fully consistent with classical literature. Tongren have read this procedure will definitely benefit! Spared the outcome here, especially to upload to share with you friends. Tongren also welcome to provide more excellent program. Documentation required as a result of N = 1024 sub-carrier OFDM, to run this process will take 2 minutes-3 minutes.)

求传递函数的一般格式，通过该程序，我们基本上能写出求任意的传递函数的式子(The general format of the transfer function of demand。Through this program, we can write the formula basically seeking arbitrary transfer function)

在土工三轴试验中应用该方法使得试样的变形测量更加简便。通过使用高精度标定板，对该数字图像测量方 法进行了精度分析，结果表明亚像素角点检测方法的轴向和径向测量的标准差都达到了0．02个像素，相对测量精度达到10‘4 数量级。(Triaxial tests in application of this method makes it easier specimen deformation measurements. By using high-precision calibration board, the digital image analysis to measure the accuracy of the method, the results of the standard deviation to measure the axial and radial table Minya pixel corner detection methods have reached 0.02 pixels, relative measurement accuracy of 10 ' 4 magnitude.)

这是一个混沌神经网络的matlab程序，可用于实现基于混沌神经网络的预测和建模。(This is a chaotic neural network matlab program for chaotic neural network-based forecasting and modeling)

快速傅里叶变换 它的主要功能是用fft变换然后识别文字(FFT ,it is used to fft and recogonize chinese )
