这是一个非局部均值算法实现工具和相关实验数据，主要用来实现图像增强和降噪应用(This is a non-local means algorithm to achieve the tools and related experimental data, mainly used for image enhancement and noise reduction application)

When a UE moves away the serving eNodeB (eNB) and becomes closer to the neighbouring eNB (see fig.1), the strength of desired received signal decreases and the ICI increases.The impact of ICI in LTE downlink can be analysed according to the received signal to interference and noise ratio (SINR) of UEm on resource block n (RBn) as

实现了文献《非线性函数耦合的Chen吸引子网络的混沌同步》的同步仿真(To achieve the literature, " Chen coupled nonlinear function of chaotic attractor network synchronization" synchronous simulation)

一些自编译的滤波器，包括同态滤波，高斯滤波，巴特沃斯滤波，理想滤波，中值滤波，均值滤波等希望对大家有所帮助(Some self compiled filter)

根据IEEE标准算例给出的9节点网络图，利用MATLAB软件编程计算其节点导纳矩阵（含有解释）。当然，依据程序稍作修改可以求IEEE算例中的任意节点导纳矩阵。(Example is given according to the IEEE standard 9-node network diagram, using MATLAB software program to calculate the nodal admittance matrix (with explanation). Of course, some slight modifications according to the program can find examples of any IEEE nodal admittance matrix.)
