LTE下行链路OFDM中的调制方式64QAM(LTE downlink OFDM Modulation of 64QAM)

控制系统中pid控制的仿真模型，是simulink的模型的，希望对学习pid的同学有用。(control system pid control of the simulation model is the model of Simulink, pid hope that the right of students to learn useful.)

雷克子波的matlab程序，地震勘探的很基础的子波(ricker wavelet)

信号包络求法,此法为hilbert变换和微分法的matlab源程序，有注释；(envelope curve calculation)

线性编码中hamming编码Simulink仿真和结果图(Linear coding Hamming code Simulink simulation and results )

小波包分析提取振动信号中的特征频率，使用拉亚普诺夫指数的公式，AHP层次分析法计算判断矩阵的最大特征值。( Wavelet packet analysis to extract vibration signal characteristic frequency, Raya Punuo Fu index using the formula, Calculate the maximum eigenvalue judgment matrix of AHP.)

這是一個讓原始音訊可以再不改變音訊長度下，改變pitch的程式，因為如果音訊用resample，雖然可改變其音訊頻率音高，但是卻會有拉長音訊的副作用，因此設計了一個可以改善其缺點的小方法(實做paper ）(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))

介绍一下图像增强技术的背景和意义以及现代图像增强技术发展的现状，其次是介绍图像增强技术的基本算法。由于要用到Matlab进行仿真，第三章将主要介绍Matlab软件在图像处理中的功能和运用。最后将详细的介绍直方图算法的意义、性质、显示及映射，并利用Matlab进行图像增强的仿真实现且达到了论文预期的目的和满意的实验结果。(Recommend the picture to strengthen the background , meaning and current situation of strengthening the technical development of modern picture of technology at first, secondly introduce the basic algorithm that the picture strengthens technology. Because should use Matlab and carry on emulation , chapter three will mainly introduce the Matlab software function and application in pattern process. Finally detailed introduction meaning, nature, showing and shining upon, histogram of algorithm, utilize emulation that Matlab strengthened the picture to realize and achieve the anticipated purpose of the thesis and satisfactory experimental result.)
