说明：  采用FDTD计算2维光子晶体的散射和透射的可执行程序小软件，修改输入文件可用于光子晶体的建模和计算，比较好用(FDTD calculation using two-dimensional photonic crystal scattering and transmission of the executable program small piece of software, modify the input file can be used for modeling and calculation of photonic crystals, compare easy to use)

说明：  完成给定的两幅图像中差异之处寻找。显示出两幅图中哪里经过了篡改(Find the difference between the two images. Shows where the two images have been tampered with)

The system simulation I have made is about Transceiver system. It s about Direct Sequence CDMA + Ultra Wide Band Simulation,which computing BER vs SNR to display the system performance. Main Program is in maindsuwb.m, you can run the overall system to display the system performance from maindsuwb.m.
