认知无线电中基于遗传算法的频谱分配的时间开销仿真实验

这学期开了软件工程工具及其应用这么课，任老师给我们教了matlab程序设计语言，做了课程实验，自己用matlab实现了计算器，发现MATLAB确实是一门很有用得计算机编程语言，它把数值计算和可视化环境集成到一起，非常直观，而且提供了大量的函数，功能强大，工应用范围广泛。 (Opened this semester and its application software engineering tools such class, any teacher taught us matlab programming language, has done a course experiments using matlab realize their own calculators, found that MATLAB is indeed a very useful computer programming language , which the numerical computation and visualization environment for integrated together, very intuitive, but also provides a large number of functions and powerful, the broad scope of application.)

选择不同的两个函数做卷积运算，可供选择的函数有矩形窗函数，锯齿波函数和sinc函数，也可自行选择其他窗，观察选取函数的波形。(Choose a different function to do convolution function to choose a rectangular window function, ramp function and the sinc function, to choose the other window, observe the waveform of the selected function.)

产生具有Jakes功率谱的rayleigh信道，可用于无线通信仿真(generate rayleigh channel with a Jakes power spectrum，this code could be uesed for wireless communication simulation)

改进神经网络PID程序用来位置跟踪，比普通的PID位置跟踪稳定性高(PID neural network program is used to improve location tracking, location tracking than conventional PID stability)

三本书都是系统辨识方面的，其中两本非常出色为经典之作，另一本为matlab的最新的应用说明（2013b）(Three books are aspects of system identification, including two very good as the classic, the other being the matlab latest application notes (2013b))

MATLAB，紋理分析，利用GLCM來得到Entropy、homogenity、itensity、correletion、IDM、ENRGY...十多種紋理特性(MATLAB, texture analysis using GLCM to get Entropy, homogenity, itensity, correletion, IDM, ENRGY ... more than ten kinds of texture features)

实现时分秒的计数和校正实现时分秒的计数和校正(Realized and correction of minutes and seconds count)

使用Matlab开发的设计凸轮的源程序，使用了向量法的设计方法。设计了一个正弦运动规律的凸轮，程序带有较完整的注释，对于初学凸轮设计的人来说应该是一个比较好的参考。(It s the source code of the design of a cam using matlab, which uses the method of vector.)

希尔伯特黄变化学习总结，技术文档，含部分matlab代码，希望对大家有帮助(Hilbert Huang change learning summary, technical documentation, containing part of the matlab code, and hope to help everyone)
