关于QPSK调制方法的一个小的仿真，使用matlab做的(QPSK modulation method on a small simulation, using matlab to do)

这是图像融合中空间转换的MATLAB代码(This is the image fusion space conversion of MATLAB code)

<matlab程序设计与应用>教材源程序，对初学者很有用！(<Matlab programming and application> teaching material source, and is very useful for beginners! )

接收端采用的算法和程序流程与发送端发送的OFDM符号的帧结构有关系。具体的帧结构，以及定时估计，频偏估计，剩余误差跟踪的算法可参考算法说明文档。(Received OFDM symbols algorithms and program flow with the sender sends the end of the frame structure used in a relationship. Specific frame structure, and a timing estimation, frequency offset estimation, the residual error tracking algorithm can reference algorithm documentation.)

基于均方误差参数比较OFDM系统中LS和MMSE两种自适应信道估计算法的性能，程序开头都有英文注释，可以直接运行的~个人认为写得比较好，跟大家一起分享~(Based on the Mean Square Error Comparison of OFDM system parameters LS and MMSE channel estimation of two adaptive algorithms, procedures are available in English at the beginning of the Notes, you can directly run the ~ personally think that is better written, with the U.S. to share ~)

说明：  交互式可视化文本扫描工具，用于读取带有分隔数据的大型文本文件。(Textscantool is an interactive GUI to read large text files with delimited data. The tool lets you specify which columns to read and what data types to use.)

匹配滤波程序 可以得出目标的位置速度等信息(match filtering)

基于MATLAB环境下各种常用的插值算法的代码 简单明了 便于初学者学习(Based on MATLAB environment variety of commonly used simple interpolation algorithm code easy for beginners to learn)

jacobi算法求解线性方程组，迭代算法。(jacobi algorithm for solving linear equations, iterative algorithm.)

说明：  自己编的关于改进的HHT的算法的部分程序，可以运行！效果还可以(Oneself make up about the improvement of the algorithm of HHT part of program, can run! Effect can also )
