这是一个自适应的遗传算法实例， 是在遗传算法的基础上改进的， 例子是和matlab工具箱与应用书上的相似(This is an example of adaptive genetic algorithm is based on the genetic algorithm improved, for example, is matlab toolbox and application of similar books)

矢量控制是目前交流电机的先进控制方式，一般将含有矢量变换的交流电机控制都称 之为矢量控制，实际上只有建立在等效直流机模型上，并按转子磁场准确定向的控制，电机才能获得最优的动态性能。 矢量控制的基本思路是以产生相同的旋转磁动势为准则，将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流，分别加以控制，以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance. The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)

在matlab里面，构造三次样条插值函数s(x)来模拟一只飞鸟外形的上部，根据已知的测试数据。(In matlab inside, construct cubic spline interpolation function s (x) to simulate the shape of the upper part of a bird, according to the known test data.)

matlab小波分析程序，是信号处理的基础，计算十字叉丝的在不同距离的衍射图像。( matlab wavelet analysis program, Is the basis of the signal processing, Calculation crosshairs diffraction image at different distances.)

bpsk 仿真程序 自己编译出来的 可以参考一下(bpsk build out their own simulation program for reference)

在matlab环境下利用句柄图形的方法创建动态图形，绘制了光源动态反射效果示例图形。(In the circumstances the use of matlab handle graphics method to create dynamic graphics, rendering the effect of light reflection sample dynamic graphics.)

设置参数，创建输入信号,计算和显示比特误差率,绘制图形.(Set parameters, create the input signal, calculate and display bit error rate, draw graphics.)

详细讲解OFDM的资料，需要的拿去，我学习使用的资料(OFDM elaborate on the information needs of Na Qu.)

我整理的ds-cdma 的完整代码，有详解，条理分明(I order the ds-cdma full code, Xiang Jie, coherent)

该程序用matlab编写数值积分方法，包括梯形公式，Simpson公式和Romberg算法，在main.m文件测试三类算法。这是数值计算方法是必须掌握的代码。(The program is prepared using matlab numerical integration methods, including trapezoidal formula, Simpson and Romberg algorithm for three kinds of formulas in main.m file for testing. Is the numerical calculation method must master code.)
