说明：  完整的ofdm仿真程序，在matlab上实现(Complete OFDM simulation program in matlab to achieve)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations

能够非常清楚的看出幅值和时间的变化规律，不用再画时、频图(Can very clear indication of the amplitude and the change of time rule，Don t draw, frequency chart)

除去接受信号中期望信号的mvdr 自适应波束形成算法（自相关矩阵估计）(Remove accepts signals desired signal mvdr adaptive beamforming algorithm (autocorrelation matrix estimation))

matlab子程序，用于光线追迹，计算光线经过透镜面后的坐标和方向。(MATLAB subroutine for ray tracing to calculate the coordinates and direction of light through the lens surface.)
