simpleGUI_V3

This code is about short time fourier transform.

说明：  Welch法功率谱密度 Psd自功率谱 是用改进的平均周期图法来求随机信号的自功率谱估计 采用信号重叠分段，加窗函数和fft算法等计算一个信号的自功率谱估计（PSD）

Jacobi algorithm to solve linear problems

最优波束形成的方法（包括谱加权，阵列多项式和z变换、波束空间的方向采样、最大最小设计等）(optimun array processing )

ofdm精同步算法实现，包含slot_test和其他8个模块(ofdm fine synchronization algorithm, including slot_test, and other 8 modules)

这是用matlab编写的求解二维光子晶体的程序。(It is written in matlab program for solving two-dimensional photonic crystals.)

说明：  几点说明： 1、source_main.m为主函数，qpsk.m和spread.m为子函数； 2、在matlab工程目录下运行source_main.m即可； 3、为方便大家理解，特以P-CCPCH信道的处理进行了举例，若大家认为资料有用的话请回帖， 我会将整个WCDMA下行信号源的matlab代码提供给需要的人； 4、为方便初学者学习，特提供了我自己开发时参考的3GPP资料，并在关键位置做了记号。 (Some explanations: 1, source_main.m main function, qpsk.m and spread.m as Functions 2, matlab project directory can be run source_main.m 3, to facilitate us to understand, especially for P-CCPCH channel processing of the example, if we consider the information useful, please Replies, I will put the WCDMA downlink signal source matlab code available to people in need 4, for the convenience of beginners to learn, especially when providing a reference to my own development 3GPP information, and in key positions in the mark.)

基于matlab实现sift描述符程序，经测试可用，效果有待提高！(achieve sift descriptor， program has been tested and is available, the effect needs to be improved!)

matlab的编程资料书，一边大家分享，共同学习(matlab programming book side to share and learn together)

说明：  复杂网络研究，真实世界网络经典示例：足球队，鲸鱼群(Complex network research, real world network classic example: football team, whale group)
