说明：  荷兰Delft大学开发的insar（干涉合成孔径雷达）图像处理部分源代码，用matlab编写的。(Netherlands Delft University developed insar (interferometric synthetic aperture radar) image processing part of the source code with matlab prepared.)

本文详细的介绍了在QAM解调系统中的相位估计的方法，该方法是基于4阶的盲估计(This paper describes in detail the system in the QAM demodulator phase estimation method is based on the blind estimation of order 4)

vmware虚拟机开机自动运行，并隐藏后台运行(vmware virtual machine to start automatically and run in the background hidden)

零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)
