课程作业时的频偏估计算法开源程序

自动车床管理、数学建模大赛。最好的换刀方案,最好的检查周期,以降低成本。 (Automatic lathe management, mathematical modeling competition. The best solution for the sword, best check cycle, in order to reduce costs. )

遗传算法 ( Genetic Algorithm , GA) 是借鉴生物界自然选择和群体进化机制形成的一种全局寻优算法 。与传统的优化算法相比 ,遗传算法具有如下优点 [1 ] :1 ) 不是从单个点 ,而是从多个点构成的群体开始搜索 ;2) 在搜索最优解过程中 ,只需要由目标函数值转换得来的适应值信息 ,而不需要导数等其它辅助信息 ;3) 搜索过程不易陷入局部最优点 。数学建模中常用的matlab算法，遗传算法，内容详细，包括PDF版本的详细的算法实现过程；

说明：  一本非常经典的书，INTRODUCTION TO MATLAB FOR ENGINEERING STUDENTS，国外很多著名大学学习Matlab就用的这本教材(This book, INTRODUCTION TO MATLAB FOR ENGINEERING STUDENTS, is a very good book.)

基于matlab的小波包使用电子书籍。可以方便大家直接使用matlab工具包进行小波变换(based on the wavelet packet Matlab use of electronic books. Can facilitate direct use Matlab tool kits wavelet transform)

说明：  matlab代码，新进的emd分解工具，比小波效果好(Matlab code, the new EMD decomposition tool, is better than wavelet)

时间序列数组的创立和数据文件读取(金融工具箱/Financial Toolbox/fints/ascii2fts)(The creation of an array of time series and data files to read (the financial toolbox/Financial Toolbox/fints/ascii2fts))

This simulation plots the Effective SNR of and OFDM as a function of Output Power Backoff from 0 to 9.5 dB, for three different number of carriers.

使用Matlab编程实现发送端信源编码（图像压缩）和接收端信源解码（图像重建），其中的编解码算法可采用基于DCT变换的JPEG图像压缩标准；测试图像加噪，然后对去噪后的图像进行压缩与重建，分析压缩性能；研究基于下采样和内插的图像压缩算法；可将8bit/pixel灰度图像扩展至24bit/pixel彩色图像，或者采用无损压缩算法对图像压缩。(Sender using the Matlab programming source coding (image compression) and the receiver source decoding (image reconstruction), one of the decoding algorithm can be used DCT-based JPEG image compression standard test image with noise, then the denoised image compression and reconstruction, compression performance analysis of down-sampling and interpolation based on image compression algorithm 8bit/pixel grayscale images can be extended to 24bit/pixel color images, or the use of lossless compression algorithms for image compression. )

指纹灰度图像的matlab代码，文件附带指纹图像(Gray-scale fingerprint image matlab code, documents attached to the fingerprint image)

说明：   该程序实现时域LMS算法，并用统计的方法仿真得出不同步长下的收敛曲线( Of the time domain LMS algorithm program implementation and use of statistical methods are not synchronized long simulation shows the convergence curve under)
