单次脉冲产生,或者周期脉冲产生.周期时间或脉冲宽度可以调节.(Single pulse, or cycle pulse. Cycle time or pulse width can be adjusted.)

说明：  提出了正交频分复用(O FDM ) 系统中一种新的载波频偏估计算法L 载波频偏估计过程可分 为获取和跟踪, 其中, 获取过程和时间同步是同时完成的L新算法可实现的最大载波频偏获取范围 是整个信号带宽的一半L新的跟踪算法是一个最大似然算法, 在加性白噪声高斯信道(AW GN ) 下, 当N (训练序列长度的一半) 等于128 时, 其性能比Schm idl 算法提高约7127 dB 在多经信道下, 当 信噪比不是很高时, 新算法仍具有优势L(new carrier f requency offset est imat ion scheme in o rthogonal f requency division mu lt ip lex ing (O FDM ) system is p ropo sed.

读取MODIS数据的方法及转换PDF格式为二进制格式的方法(the method of reading MODIS data and conversing the PDF format to the binary format)

《自适应滤波器》第五章代码，很详细，值得推荐(Chapter adaptive filter code, very detailed)

This book is : Basics of MATLAB and Beyond - Andrew Knight, you can use this book with file code i uploaded before. Well done !

FFT源代码，该源代码比较全面，稍微改动即可使用，欢迎下载，谢谢！(FFT source code, the source code is more comprehensive, you can use a little change, welcome to download, thank you!)

说明：  最优化计算一书中二次规划源代码，已通过测试，可直接运行！(Optimization calculation of a book quadratic programming source code, and have passed the tests, can be directly run.)

低通滤波器，每句程序都有注释，易懂，还有一个实例，便于加深认识(Low-pass filter, each sentence programs have notes, easy to understand, there is an instance, to facilitate a better understanding of)

2013年“高社杯”数学建模b题，对于纵向切割的图片复原。 使用方法：打开matlab，调整工作目录为解压后的文件夹，在matlab工作框中输入Problem1即可(2013 " High Society Cup" Mathematical modeling b title picture for longitudinal cutting recovery. How to use: open matlab, adjust working directory is unpacked folder work in matlab can enter Problem1)
