This describes two ways of rotating an image 1. With black dots in between 2. Clear image received after enlarging then rotating then reducing size again

openExcel :用Matlab打开启动Excel服务器，并返回Excel活动页的句柄H jitt : 利用传入的周期向量，计算频率抖动 norma : 把计算得到的向量平均采样为30个点 interest ： 复利计算方法 myvad : 通常vad算法只能得到汉语普通话一声、二声和四声的语音，对于三声，中间因为有嘎裂，就是突然基频变得很低并且不规则，vad算法把一个音节往往切分为两个音节，myvad解决普通话三声的问题 (Open Excel sever by Matlab, and returen a handle of Excel active sheet)

说明：  最小均方误差（LMS）自适应滤波器的matlab函数 lms.m(matlab function lms.m : LMS adaptive filter)

说明：  这是一个对比仿真实验： 基于复信号构造系统，生成IQ数据，进行QAM复调制，然后进行复解调，给出调制前后的频谱： 之后在用传统的载波调制的方式重新在做一遍，给出调制前后的频谱(This is a comparative simulation experiment: Based on complex signal construction system, IQ data is generated, QAM complex modulation is carried out, then complex demodulation is carried out, give the spectrum before and after modulation After that, the traditional carrier modulation method is used to do it again, give the spectrum before and after modulation)

对正交频分复用的仿真，主要针对其简单原理进行仿真(On orthogonal frequency division multiplexing of the simulation, the main principle for its simple simulation)
