OFDM Simulation Using Matlab

Largest of 2 no. C++

Matlab code for simulating Clayton copula, Frank copula, Gumbel copula, Gaussian copula and Student t-copula

说明：  最小二乘法仿真，系统辨识算法，经典数学算法(Least squares simulation)

说明：  光纤LP51模式,光纤模式计算，纤芯模式，有效折射率(Fiber LP51 mode, fiber mode calculation, fiber core mode, effective refractive index)

说明：  图着色，采用图论的方法进行图形着色，首先采用相邻矩阵，计算顶点之间的关系(Graph coloring. Graph coloring is done by graph theory. First, the adjacent matrix is used to calculate the relationship between vertices.)

：给出了一种提取特征点的新方法和合理的特征不变量。该方法根据三角不等式原理利用第三边与另 外两边之和的比值大小来确定角点，以特征点和它相邻的两个特征点所形成的两条直线的夹角正切值以及三角形 第三边与另两边和的比值作为特征不变量。这种特征提取的方法简单，并且由于扩大了模板取值范围，使识别效果受特征点漏检的影响较小。实验表明，该方法不仅简便，而且效果良好。(: In this paper, a new feature point extraction method and the characteristics of rational invariants. The method is based on the principle of triangle inequality with the use of the third side and both sides of the ratio of the size to determine the Corner to feature point and its two adjacent feature points formed by the angle between two tangent linear and the third triangle on both sides and edges with another feature of the ratio as a variable. This feature extraction method is simple, and as a result of the expansion of the scope of the template values to identify the effect of feature points by the impact of smaller undetected. Experiments show that the method is not only simple, but effective.)

mimo 2*1的仿真程序，和原始的alamouti的论文里的仿真图是一样的(mimo 2* 1 of the simulation program, and the original alamouti s thesis is the same as the simulation map)
