本程序是对64QAM-OFDM的调制解调及加AWGN的简单程序。做成GUI形式，能方便地梳理清楚整个过程。调制解调过程中加入了导频和CP循环前缀，可观察EVM和EbN0-BER曲线。(this program is about the modulation and demodulation based on Matlab.A simple program to familiar with the process of 64QAM-OFDM.Using reference and CP. You can observe EVM and the figure of EbN0-BER)

用平面波展开法计算二维声子晶体带隙,对于初学matlab的同学会有帮助，相关分析过程的matlab方法。( Computation Method D phononic bandgap plane wave, Matlab for beginner students will help, Correlation analysis process matlab method.)

在matlab的环境下实现了自回归移动平均模型（arima）(Matlab environment in the realization of the auto-regressive moving average model (arima))

这个是我对于模糊pid控制自己进行的simulink仿真，很有用。(This is my fuzzy pid control themselves for the simulink simulation, very useful.)

说明：  用的是图像处理的知识 非常实用 可以参考学习(Using a very practical knowledge of image processing can refer to learn)

RGB TO GRAY CONVERT WITHOUT USING RGB2GRAY SYNTAX BY RAJESH

说明：  simulink 通信仿真手册 里面详细介绍了每个模块的作用和详细参数设置(communication simulation simulink Manual which details the role of each module and detailed parameters set)

it is the program for rls algorithm for a sound wave

基于SVR的非线性系统故障诊断，假设非线性系统在1.4s~1.6s期间发生系统参数变化故障(SVR-based fault diagnosis of nonlinear systems, assuming nonlinear systems in 1.4s ~ 1.6s failure occurred during the parameter variations)

说明：  对图像进行DWT变换后的图形结果，如上传所示！(DWT transform the image of the graphical results, as shown upload!)
