灰色关联分析中，计算关联度系数，以寻找出两个变量间的关联程度(This program will caculate the calculation of correlation coefficients in order to find out the correlation between two variables in the Grey relational analysis)

说明：  该程序实现OFDM系统中块状导频的信道估计，块状导频用于时变较慢的多径信道，可以估计出每个载波上的信道传输情况。(The programme realizes channel estimation with block pilots.)

建立ARMA模型，进行数据的预测，效果很好，这里是其中的代码(the code of the ARMA)

Matlab Code for simulation of a MIMO systems

关于DOA估计，即波达方向估计的matlab程序，经过检验可以直接运行，适合于刚入门的同学(About DOA estimation, DOA estimation matlab program can be run directly tested, suitable for students just getting started)

说明：  利用传播算子，进行阵列信号角度估计，运算快，不需要峰值搜索。(Use propagator conduct array signal angle estimation, fast operation, no peak search.)
