中文说明：毕业设计有用，通过虚拟阵元进行DOA估计，最大似然（ML）准则和最大后验概率（MAP）准则，matlab程序运行时导入数据文件作为输入参数，MIMO OFDM matlab仿真,基于分段非线性权重值的Pso算法。
English Description：
Graduation design useful. The virtual array for DOA estimation, maximum likelihood (ML) criterion and the maximum a posteriori (map) criterion, the matlab program is running into data files as input parameters, the MATLAB simulation of MIMO OFDM, based on piecewise nonlinear weights of PSO algorithm.
