使用matlab simulink 编写的钟摆运动(use matlab simulink to do a clock move)

本文详尽阐述了如何在matlab环境下使用matlab 7.0，教程，pdf版本(This article elaborates how to use the matlab environment matlab 7.0, tutorial, pdf version)

THIS IS ABOUT MATLAB IMAGE BINARIZATION

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

QPSK是通信信道中一种很好的调制方式，对于其性能参数进行了仿真，信道以及噪声选择可以根据代码自由改动。对学习无线编码很有用处。(QPSK is a good communication channel modulation, the performance parameters for the simulation, channel and noise free choice can be altered according to the code. Learning wireless encoding useful.)

说明：  该程序展示出了多普勒压缩系数与距离之间的关系，也即显示出了单频矩形脉冲的距离分辨力。(The program demonstrates the Doppler compression factor and the distance between them and also that showed single-frequency rectangular pulse range resolution.)

自己编写的求解本证值的程序，用以对崩政治求解方法的理解，也可以做成其它线性代数程序的子函数(their preparation for the certification of the value of the procedure to solve the political collapse of understanding, can also cause other linear algebra procedures Functions)

Good research paper for cooperative spectrum sensing for cognitive radio

该程序实现了对于光纤中的脉冲在光纤传播的演化过程(The program implements the evolution of the optical fiber pulse propagation in optical fibers)

arima建模，用过计算aic获得最佳的p、q值，建立arima模型对时间序列进行预测(arima forcast program)
