说明窗函数为文献窄时，STFT无频域的定位功能；(Note, when a narrow window function of literature, STFT-free frequency domain positioning function )

说明：  数值分析插值问题，还有用处啊 ！！！！大家可以好好学习一下。(Numerical Analysis of interpolation problems, but also the usefulness of ah! ! ! ! We can learn about.)

介绍matlab 的葛哲学的书，很好的反映了如何在matlab 中实现信号的分析和处理(Introduction matlab' s Gezhe school books, a good reflection of how to implement matlab signal analysis and processing)

系统地阐述了低密度校验码基于图模型的编译码思想，介绍了密度进化理论，对影响低密度校验码纠错性能的两个主要因素——度序列设计和围长设计进行了深入分析，详细介绍并设计了LDPC的编解码(Systematic exposition of the LDPC graph model based codecs idea, introduces the density evolution theory, the two main factors that affect the performance of LDPC error correction- the degree of sequence design and girth design depth analysis, detailed and designed LDPC codec)

把txt格式的数据文件引入matlab中进行fft，输出四个图( Txt data file format introduced conducted matlab fft, the output of the four figure)

ransic用于减少错配点，方便可行，经本人验证，程序可行，欢迎下载(ransic used to reduce the mismatch points, convenient and practical, as I verified, the program feasible, welcome to download)

该程序可实现图像四方向频谱划分，通过该程序，衣服图像四方向的信息会很好的展现出来。(This program can be divided into the spectrum of image four directions, through the program, four-direction image information clothes would show up well.)

说明：  利用PTS技术降低峰均比，并作出与未使用降低PAPR技术的CCDF对比图形(Comparing with OFDM system without PAPR reduction techniques,figure the CCDF using PTS technique.)

Motion vector detection

基于MATLAB的分水岭算法，运用分水岭原理对图像进行分割处理。(Watershed algorithm based on MATLAB, using the principle of the watershed image segmentation.)
