多用户MIMO算法仿真，包括BD,ZF,MMSE等(multiuser MIMO simulation)

这是一个基于GUI系统。 GUI是在命令行调用通过键入“ui_start”。 GUI是自我解释性。(This is a GUI-based system. GUI is invoked on the command line by typing " ui_start" . GUI is self explanatory.)

生成一个规则LDPC码的教研矩阵H，其行数(越大越好)为列数的一半，行重为6，列重为3，任意两行没有围长为4的圈 使用方法：H=HGrandom2(m,n)。m表示行数，n表示列数(rules of a generation of research LDPC matrix H, its (larger the better) half of the series, re-6, series of three, two arbitrary line is not girth of the ring used four methods : H = HGrandom2 (m, n). Said a few m, n Columns)

这是两个根据Kemp-Riddel半经验公式编写的源代码，可以用来求解再入弹头驻点及非驻点的热流密度。(This is two source code according the half experience formula of Riddel Kemp , can be used to solve the heat flux of stagnation point and the heat stationary point.)

CARS变量选择方法能够在一定程度上克服变量选择中的组合爆炸问题，筛选出优化的变量子集，提高模型的预测能力( Competitive Adaptive Reweighted Sampling method for variable selection.)

这是加权网络中节点强度和权重都是幂率分布的模型。(This is a node-weighted network strength and weight distribution are the model of power.)

用matlab编写雷达发射的线性调频信号(Written by radar chirp signal with matlab)

里面包含主元分析PCA的Matlab代码，包括提取主元，求方差贡献率，绘制贡献率直方图等(Which contains the principal component analysis PCA of the Matlab code, including the extraction of the main element, seeking variance contribution rate, contribution rate of histogram mapping, etc.)

遗传算法及其应用实例，用matlab实现，讲解很详细(Genetic algorithm and its application examples, using matlab to achieve, to explain in great detail)
