最大似然法德matlab仿真程序，用在ofdm系统中很好！！！与大家一起享用(Maximum Likelihood France and Germany Matlab simulation program used in ofdm system good! ! ! Together with everyone to enjoy!)

汇集了几个经典的matlab程序，大家共同学习(A collection of several classic matlab program, we learn together)

GUI Fourier series representation

逆合成孔径雷达（ISAR）转台成像仿真，使用MATLAB(ISAR turntable imaging simulation)

说明：  验证四象限变频器的基本充放电功能，实现并网(Testing the charging-discharing function of four-inverter , achieving grid conneected.)

对任意大小的灰度图像进行zig-zag变换和反变化，或者是对DCT之后的图像进行zig-zag变换，确定其中频信息。(Any size of gray-scale images in zig-zag transform and anti-change, or is the DCT of the image after the zig-zag transform, to determine which frequency information.)
