快速谱峭度工具箱，由法国人Antoni编写(Fast spectral kurtosis toolbox, written by French Antoni)

This matlab code describes soft demapper (soft bit) for different modulation types: BPSK, QPSK, PSK 8, QAM 16, QAM 64, which are considered for turbo encoding/decoding. And simulation results are also presented.

设计Spectral methods、Probability and Stochastics等(Other design Spectral methods, Probability and Stochastics)

这是一个整理后比较全面的数学建模所用到的基本的十种计算方法的matlab源代码！(This is a more comprehensive sort out the mathematical modeling used by dozens of the basic method of calculating the matlab source code!)

处理降雨量日志数据的小程序，去掉异常值，换算，统计，作图(Applet rainfall log data, remove outliers, conversion, statistics, mapping)

绘制一个位于坐标轴中的目标按钮，通过改变滑动条来移动目标按钮的位置，并同时显示它的坐标。(Draw a destination button located in the axis, and by changing the slider to move the position of the target button and its coordinates are displayed simultaneously.)

利用stft实现了跳频信号的跳周期估计 简单的进行了跳频信号的仿真，然后利用短时傅里叶变换对跳频信号进行分析，再对得到的时频矩阵提取时间平面，对时间序列去直流，进行傅里叶变换，最后实现得到跳周期。(estimates the hopping time of the sfh by stft )

此程序主要用于图像的匹配、配准，编程开发环境为MATLAB，是学习图像处理的同学很好的参考资料。(image matching)

Spring movement Simulation Matlab / Simulink model(Spring movement Simulation)

该程序是利用电磁波测得两处之间的距离，程序不错，稍加修改即可测得很多距离值。(It tells us how to calculate the distance between two places ,using the EM )
