4g的核心技术：关于MIMO技术当中的空时编码(4g core technology: coding on the MIMO-OFDM)

采用加权网络中节点强度和权重都是幂率分布的模型，双向PCS控制仿真，能量熵的计算，重要参数的提取，基于人工神经网络的常用数字信号调制，应用小区域方差对比，程序简单。( Using weighted model nodes in the network strength and weight are power law distribution, Two-way PCS control simulation, Energy entropy calculation, Extract important parameters, The commonly used digital signal modulation based on artificial neural network, Application of small area variance comparison, simple procedures.)

另外一个程序，同样实现matlab下的多重线性回归~(Another program, under the same realization of the multiple linear regression matlab ~)

用matlab语言 分别判断出三个圆的圆心，并且求出这三个圆之间的距离(Matlab language were used to determine three of the center circle, and obtained the three round distance between)

说明：  该算法包含极大似然估计的梯度算法和快速ica算法，已经调试成功过，调试时注意所给信号x是行向量还是列向量(The algorithm contains the maximum likelihood estimation of the gradient method and fast ica algorithm, has been debugged, debugging attention given signal x is a row vector or column vector)

matlab中如果需要更改对话窗口的图标，则需要自己在程序中加入代码，文件包括3个窗口的图标更改程序。(matlab dialog window, if you need to change the icon, you will need to add your own in the program code, files including three windows icons change the program.)

this is a pdf book talking about matlab and its benifits for developpment and encountering new specifications in object tracking

柔性机构优化设计程序，主程序为topm，只需要输入行列的单元数、体积份数、惩罚因子就可获得所需的柔性机构(compliant mechanisms to optimize the design process, the main program for the topm, only need to enter the ranks of the unit number, the volume of shares to obtain the necessary penalty factor can be compliant mechanisms)

高阶谱工具包，用于计算信号的各阶谱结构，得到信号在高阶谱情况下的重要特征(higher-order spectral toolkit)

很好的Adaboost自学实例，简单易懂(A simple but robust Adaboost exmaple, which is easy enough by self-learning)
