本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

说明：  产生伪随机码，长度是任意2的指数次，非常可靠的程序(can generate the presedorandom code, any length is OK)

很完整经典的多输入多输出正交频分复用技术的联合仿真，用MATLAB 搭建仿真平台，包括个其整个过程，有20个M文件及很多个数据文件，可对MIMOOFDM技术进行全面评估(mimo-ofdm matlab)

能对两个信号进行相关性分析，在进行分析时，注意不同的方法可能意义不太一样(Correlation analysis can be performed on the two signals)

matlab实现：高斯消元法，LU分解法，迭代法，奇异值分解，乔累斯基分解法，gauss迭代解线性方程组，jacobi迭代解线性方程组(matlab implementation: Gauss elimination, LU decomposition, iterative methods, singular value decomposition, Cholesky decomposition, gauss iterative solution of linear equations, jacobi iterative solution of linear equations)

DDS(快速正交调制）生成正弦波形，利用相位累加字进行累加，查找查找表内容输出正弦数据，在通信领域应用很多，我采用的是matlab的simulink进行前期仿真(DDS (fast quadrature modulation) to generate sine wave, the use of the word to accumulate phase accumulation, content output sine lookup table lookup data in many applications in the communications field, I used to pre simulink of matlab simulation)

MATLAB的迭代静校正代码，原创……………………(MATLAB iterative static correction code, original ... ... ... ... ... ... ... ...)

波束空间的MUSIC算法，在阵元误差校正和ＤＯＡ估计时很实用～～(Beam space MUSIC algorithm, the array element error correction and DOA estimates very practical ~ ~)

This code perform the DCT and quantization on all the channels without any sub-sampling and for the compression of color images, they are first converted to the YCbCr color format and vice versa, use the function rgb2ycbcr and ycbcr2rgb.
