Atomatic Gain Control

基于PCA的图像融合算法，用matlab实现(Image Fusion based on PCA ，Completed by matlab)

说明：  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中用PSD法绘制信号功率谱,可得到信号的频谱幅度。(PSD method using matlab draw the signal power spectrum, the spectrum available to the signal amplitude.)

　传统的信号理论，是建立在Fourier分析基础上的，而Fourier变换作为一种全局性的变化，其有一定的局限性。在实际应用中人们开始对Fourier变换进行各种改进，小波分析由此产生了。小波分析是一种新兴的数学分支，它是泛函数、Fourier分析、调和分析、数值分析的最完美的结晶；在应用领域，特别是在信号处理、图像处理、语音处理以及众多非线性科学领域，它被认为是继Fourier分析之后的又一有效的时频分析方法。 小波变换与Fourier变换相比，是一个时间和频域的局域变换因而能有效地从信号中提取信息，通过伸缩和平移等运算功能对函数或信号进行多尺度细化分析（Multiscale Analysis），解决了Fourier变换不能解决的许多困难问题。(The traditional signal theory, is based on Fourier analysis based on Fourier transform, and as a kind of global change, it has some limitations. In the actual application of Fourier transform people began to various improved, wavelet analysis produced. Wavelet analysis is a new branch of mathematics, it is functional, Fourier analysis, harmonic analysis, numerical analysis of the crystallization of the most perfect In the fields of application, especially in signal processing, image processing, audio processing as well as many nonlinear scientific fields, it is considered to be the Fourier analysis after another effective time-frequency analysis method. Wavelet transformation and Fourier transform, compared is a time and frequency domain and the local transform can effectively extract information from signal, through the telescopic peace shift etc operation function of the function ? )

simulink的仿真有两个阶段：一个为初始化，这个阶段主要是设置一些参数，像系统的输入输出个数、状态初值、采样时间等；第二个阶段就是运行阶段，这个 阶段里要进行计算输出、更新离散状态、计算连续状态等等，这个阶段需要反复运行，直至结束。(simulink simulation has two phases: one for initialization, this stage is mainly to set some parameters, such as the number of input and output system, initial state, the sampling time second stage is the operational phase, the Stages to calculate the output, update the discrete state, continuous calculation of the state, etc., this stage requires repeated runs to the end.)
