QPSK Modulation and Demodulation with AWGN , Performance comparision against on BER / EB/NO ratio.

时频分析工具包，可用于非平稳信号处理，for matlab(This is the Time-Frequency Toolbox, a collection of about 100 M-files , developed for the analysis of non-stationary signals using time-frequency distributions. It consists in groups of signal generation files, processing files and post-processing files (including visualization tools). The toolbox contains numerous algorithms for time-frequency signal analysis, with special emphasis on quadratic energy distributions within Cohen s class and the affine class, including most recent developments based on reassignment. The Time-Frequency Toolbox has been developed by Francois Auger, Olivier Lemoine, Paulo Gonlv and Patrick Flandrin during the years 1995-1996. Later, modifications for Matlab 5 were made available.)

说明：  这是matlab的otsu处理图象的算法，请高手们指正(This is the Otsu Matlab image processing algorithms, experts used the correct)

this is a code for remote sensing application

时频分析方法中的短时傅里叶变换，可用于信号处理。(The time-frequency analysis of short-time Fu Liye transform method, can be used for signal processing.)

说明：  另一种潮流计算程序，本程序使用C语言编写(Another flow calculation procedures, the procedures using the C language)

在普通无权网络基础上定义加权结构熵，即用来计算赋权网络的结构熵(The weighted structure entropy is defined on the basis of the ordinary unauthorized network, that is, the structural entropy used to calculate the weighted network.)

word版的matlab教程，能够支持在线的命令及参数的查询(word version of matlab tutorials, can support online orders and parameters of the query)

说明：  小波变换去噪算法，可以自己改变阈值函数与分解层数(Wavelet transform denoising algorithm can change the threshold function and decomposition level by itself)
