通信系统中的接入信道部分进行仿真与分析,运用MATLAB软件对接入信道部分进行设计，并逐步地对各个模块进行分析、仿真与验证。(Communication systems part of the access channel simulation and analysis)

find out minimum spanning tree

说明：  太阳能光伏电池的matlab/simulink 仿真模型，可以对光伏特性进行仿真。(Solar photovoltaic cells, Matlab/Simulink simulation model, on the photovoltaic properties of the simulation.)

这是一个数字调治解调器，非常经典的。经过本人仿真可以实现(This is a digital modulation modems, very classic. After I simulation can be achieved)

This program applies Upsampling on a speech file.

用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

MATLAB图形用户界面的几点思考,很不错的(MATLAB graphical user interface Reflections)

这是一个Matlab实现的图像Sparcy变换的程序，有助于了解多尺度变换。(This is a Matlab implementation of the image Sparcy transformation process, help to understand multi-scale transformation.)

信号加噪方法，采用平均功率算法计算信噪比。(Signal plus noise method using average power algorithm to calculate the SNR.)

常用的图像融合评价指标，包括熵，交叉熵等等，分享一下，欢迎下载(calculate the entropy of information of fusion image)
