该文档详细介绍了4G LTE下的MIMO OFDM的工作原理(very good document for get knowledge of 4G MIMO OFDM)

利用matlab设计滤波器，有原理说明及其matlab的代码实现(A filter was designed using matlab, there are principles of note and its matlab code to achieve the)

雷达定位算法，通过收集三个雷达的数据确定飞行物的坐标位置(Radar positioning algorithm, by collecting three radar data to determine the coordinates of the location of flying objects)

以4*4为模板在一幅灰度图像中寻找像素值大于给定阈值的点(Of 4* 4 in a gray image as a template to find the pixel value is greater than a given threshold point)

《精通Matlab图像处理》一书的例程，入门必备。共17个文件夹，让你从入门到精通！！(Matlab Study_《Proficient in MATLAB image processing》)

求根MUSIC算法源程序，实现波达方向估计(Root MUSIC algorithm source code, direction of arrival estimation)

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)

利用MATLAB进行仿真，对图像进行dct变换，探究变换后与原图像的差别(Using MATLAB simulation, the image dct transform, transform and explore the difference between the original image)

该程序利用三阶科斯塔斯环实现锁相环结构，有效的估计输入信号的相位变化，在通信系统的同步上广泛应用。(The program uses the third-order Costas loop to achieve phase-locked loop structure, effectively estimate the phase change of the input signal, widely used in synchronous communications system.)
