本程序利用平方环实现载波同步，使用锁相环进行跟踪相位偏移(This program makes use of the square ring to achieve carrier synchronization, with the use of PLL to track the phase shift)

利用3*3模版实现对图像的膨胀,是比较基础的图像膨胀的算法(The use of 3* 3 stencil of the image to achieve the expansion, is the basis of comparison of image expansion algorithm)

说明：  ID3算法进行分类，二叉树分类，包括数据集(ID3 algorithm for classification, binary tree classification)

一种适用于多自由度的自然激励技术，可以实现从随机响应信号中提取自由振动信号。(A multi-degree of freedom for the natural excitation technique, can extract from the random response signal free vibration signals.)

模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型 (Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details: op_channel = additivenoise(input_signal) mathematical Model: s(t) input signal to channel (=sig_ip) n(t)additive random noise process added by channel (=noise_mat) a(t) attenutation factor , here it is taken as random(=att_fact) out put signal r(t) = a .* s(t)+ n(t) an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal )

Three different kinds of trajectory generators. including linear simple.Linear accelerated. and circular

三相有源滤波器模型，matlab环境下搭建，滤波效果良好，且在负荷变化时能够迅速跟踪谐波电流变化并进行补偿。(Three-phase active filter model, matlab environment to build, the filtering effect is good, and when the load changes can be quickly tracked changes and harmonic current compensation.)

matlab教程 不过 大家看看 比较实用哦!内容很详细()
