QAM调制仿真程序，在AWGN和瑞利衰落信道下仿真，适用于初学者。(QAM modulation simulation program, in the AWGN and Rayleigh fading channel simulation, applicable to beginners.)

This code calculated the LDP histogram and is based on B Zhang, Y Gao, S Zhao & J Liu, "Local Derivative Pattern Versus Local Binary Pattern: Face Recognition With High-Order Local Pattern Descriptor," Image Processing, IEEE Transactions on, vol.19, no.2, pp.533,544, Feb. 2010

这是一个基于偏微分方程的图像处理问题的非线性平滑滤波器的程序!(This is a partial differential equations based on the question of image processing procedures for non-linear smoothing filters!)

用于绘制混沌图形的henon程序，其中有著名的罗伦兹图(Chaos for graphics rendering henon procedures, including the famous Lorenz map)

本仿真采用dq原理检测谐波,采用PI闭环控制策略(This simulation uses DQ principle to detect harmonic, and adopts PI closed-loop control strategy)

提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观 法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is ​ ​ divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)
