MatLab code for simulation of a 4PPM communication system.

这是matlab版的视频水印，仅供初学者参考。(This is videowatermark code.)

基于无轴承同步磁阻电机非线性解偶控制的径向力模块仿真(Simulation modules radial forces bearingless linear synchronous reluctance machine control decouple)

说明：  自相关函数及互相关函数编程(Autocorrelation function and its programming)

使用下面的参数设计信道均衡器，其中使用两个独立的随机数发生器，一个用x(n)来表示，用来测试信道；另一个用v(n)来表示，用来模拟接收器中的加性白噪声的影响。序列x(n)是x(n)=±1的伯努利序列，随机变量x(n)具有零均值和单位方差。第二个序列v(n)具有零均值，其方差由信噪比决定。均衡器有11个抽头。(Use the following parameter design of channel equalizer, which uses two separate random number generator, one with x (n) to indicate, to test the channel the other with v (n) to indicate to simulate the receiver in The additive white noise. Sequence x (n) is x (n) = ± 1 of the Bernoulli sequence of random variable x (n) with zero mean and unit variance. The second sequence v (n) has zero mean, its variance decision by the signal to noise ratio. There are 11-tap equalizer.)

此m文件时实现MATLAB实现函数，Gabor滤波器的傅里叶变换为谐波和高斯函数各自傅里叶变换的卷积。 (Gabor transform！)

自动控制原理实验面向对象 电气工程及其自动化专业、自动化专业、电子信息科学与技术专业前修课程 或要求 《模拟电子技术》、《自动控制原理》、《控制系统MATLAB程序设计》、《电机及拖动基础》等专业基础课。 (automatic control MATLAB)

详细的介绍了有关matlab绘图方便的操作，对初学者非常有用(For details about the matlab graphics and convenient operation is very useful for beginners)

说明：  利用MATLAB语言来实现Levinson-Durbin递推算法，并估计AR模型参数，从而对正弦信号加白噪声进行功率谱估计。(Using MATLAB language to implement Levinson-Durbin recursive algorithm, and estimate the AR model parameters, thus sinusoidal signal plus white noise power spectrum estimation.)

数字图像中心点的确定、定位、图像的裁剪、以及数字图像样本的输出等。(To determine the center of the digital image, positioning, image cropping, digital image sample output.)
