课设的信号特征提取、信号消噪例子

说明：  多项式在数学中是重要的内容，在很多学科中有重要应用！(Polynomials in the content of mathematics is important in many disciplines have important applications!)

用matlab实现数据的导入与导出 内含经过调试的详细代码(The data input and export with detailed code)

在陀螺仪测试中，实现ALLAN方差法分析动态数据，得到五个主要参数(Gyroscope test to achieve the the ALLAN variance analysis of dynamic data, five main parameters)

adaptive channel equalizer simulink model

這是一個可以自動尋找图像中的長方形, 正方形, 圓形, 菱形的程式(1- Read the RGB (colored) image in from user. 2- Convert image from (RGB) colored to gray image. 3- Threshold the image (convert gray image to binary image). 4- Invert the binary image (in order to speed up the time of processing). 5- Find the boundaries concentrate. 6- Determine shapes properties (ratio of dimensions, roundness). 7- Classify shapes according to its properties. )

求解无约束问题最优化问题的基础方法之一：高斯牛顿法(Gauss-Newton methon)

说明：  基于matlab的子程序，可以进行任意通信信号的升余弦滤波(Subroutine based on matlab, any communication signals can be raised cosine filter)

说明：  本代码描述的是有关灰狼算法的研究，这个代码有详细的内容说明与简介，网络上的代码普遍有错误，本人将所有的代码全部实现并改正了错误。供大家学习参考(This code describes the research on the gray wolf algorithm. This code has detailed description and introduction. The code on the network is generally wrong. I have implemented all the code and corrected the error. For everyone to learn reference)

结合PCA的尺度不变特征变换(SIFT)算法，针对EMD方法的不足,用于时频分析算法，基于kaiser窗的双谱线插值FFT谐波分析，匹配追踪和正交匹配追踪，包括广义互相关函数GCC时延估计。

说明：  自动阈值分割算法，算法是Wellner s adaptive thresholding。(Automatic threshold segmentation algorithm, the algorithm is Wellner' s adaptive thresholding.)
