Mimo with Rayleigh channel and Zero Forcing

用matlab求复杂网络的节点的度、聚类系数、路径长度等，是关于有向网络的。(Complex networks using matlab and node degree, clustering coefficient, path length, to the network.)

最优化方法 最速下降法程序 MATLAB程序(MATLAB program optimization method of steepest descent method)

图像分形盒维数的算法源程序.此算法是基于黑白二值图像的，因此，需要对导入的图片进行二值化处理，因此算法存在一定误差，但是此算法误差控制在4 以内(Image fractal dimension algorithm source code box This algorithm is based on black and white binary image, and therefore, need to import the picture binarization processing, so the algorithm there are some errors, but this algorithm is less than 4 error control)

将指纹图像分为好、中、差三类，然后根据典型的质量指标在各类质量中的影响度来设定相关的权重，以此可以更准确的表示图像质量，提高指纹识别的后续处理的准确性，系统的稳定性(Fingerprint image is divided into good, normal and poor, and then the typical quality indicators in the quality of the impact of various degrees to set the associated weight, this can be a more accurate representation of image quality and follow-up to deal with fingerprint recognition accuracy, system stability)

粒子群算法OptSwarm记录每个粒子的历史最优解（粒子历史最好的适应度）以及全部粒子搜索到的全局最优解。用Wg代表全局最优解，W.,1代表每个粒子的历史最优解。粒子群初始化阶段表OptSwarm的前N行与表ParSwarm中的相同，而Wg的值为表ParSwarm中适应度值的最大值对应的行。(Particle swarm algorithm OptSwarm record the history of each particle the optimal solution (particles history best fitness), and all the particles of the search to the global optimal solution. Use Wg represents the global optimal solution, w., 1 representative of each particle history to the solution. Particle swarm initial stage OptSwarm table before the line and the table ParSwarm N is same, and the value of the ParSwarm Wg for tables in the maximum fitness value corresponding line. )

BURG方法谱估计 采用BURG迭代方法计算系数，在采用AR模型的谱估计进行谱峰搜索(BURG spectrum estimation methods BURG iterative method using coefficients in the AR model spectrum estimation using the peak search)

dpsk的matlab实现，该程序含有BER的绘制方法(the dpsk program under the circumstance of matlab including BER)

FDD链路的仿真使用的是KA波段，其中在接收端涉及到多种算法（位同步算法，DD算法等）(FDD link simulation using KA band)

关于MATLAB的一些应用实例，我同学编的，大家可以看一下-(About some application examples of MATLAB, my classmates series, we can look at-)
