image fusion in average method

说明：  此为LDPC低密度校验码的编译码的原理与应用的详细介绍。包括各种信道模型下的仿真结果，有助于更好的学习通信系统的编译码过程的实现。(This is the LDPC coding and decoding LDPC codes principles and applications in detail. Including channel model simulation results, contribute to a better communication system of learning to achieve encoding and decoding process.)

说明：  先运用pca找到主要的影响变量，然后用rbf神经网络建模(First use PCA to find the impact of major variables, and then use the rbf neural network modeling)

使用MATLAB对智能天线自适应LMS算法部分进行仿真，假设共有4个天线单元(Adaptive smart antenna using MATLAB, the simulation part of the LMS algorithm, assuming a total of four antenna elements)

说明：  Load flow Gauss siedel method

对于一维各向异性问题，这里利用阻尼最小二乘的反演算法，结合RI反演数据集反演。(For one-dimensional anisotropic problems, where the use of damped least squares inversion algorithm, combined with the RI data set inversion inversion.)

无线信道建模很复杂，不同场景下的模型差异较大，这是一本讲解无线信道建模方法的经典书籍配套的matlab例程(Channel modeling is complex models under different scenarios are quite different, which is a classic way to explain the channel modeling books matching matlab routines)

将复杂网络中的邻接矩阵数据，转换成两列数据，第一列表示有向网络的始点，第二列为末点(The complex network adjacency matrix of data, the data is converted into two, the first column represents the starting point of a directed network, the second column is the end point)
