程序是OFDM系统整个发送接收过程，其中包含QPSK调制解调，快速傅里叶正逆变换，还有信道估计等过程。(The procedure is the OFDM transmitting and receiving process of the system, which includes QPSK modulation and demodulation, and inverse fast Fourier transform, and the channel estimation process.)

qam16位离散牛顿法数字预失真程序，经过测试能够正确完成，效果良好。(qam16 discrete Newton method digital pre-distortion and tested correctly to good effect)

灰色预测模型在Matlab的语言编程(基于GM（1，1）模型)自己编的，很简单。就是为了当时处理数据方便。只是预测下一个数据，如果想得到更多的预测数据，可以在添加。(Gray prediction model in the Matlab programming language (based on GM (1,1) model) own, and very simple. At that time, in order to deal with data that is convenient. Only the next prediction data, if the prediction would like to receive more data, you can add.)

用于图像识别和特征提取时的主成分分析程序，采用Matlab编写。(for image recognition and feature extraction of principal component analysis procedures, the preparation of Matlab.)

用c#编写了一套FIR窗口滤波器，其中数据段的提取来自于matlab的混合编程(Written in c# a FIR filter window, including data extracted from the mixture of matlab programming)

GNSS/INS组合导航的定位算法，18维状态空间，仿真验证程序。(GNSS/INS integrated navigation positioning algorithm, 18 dimensional state space, simulation verification program.)

2012年全国研究生数学建模-基于卫星无源探测的空间飞行器的轨道估计，里面包括详细的设计求解过程，含有matlab解算的M文件。(2012 National Mathematical Modeling graduate- satellite-based passive probe spacecraft orbit estimate, which includes detailed design solution process, the file containing the M matlab solver.)

核磁共振方法是一项尖端技术，在物理学和医学等领域有着较普遍的应用。 其无损性和高分辨率的特点是这项技术最大的优势。而利用核磁共振方法来找水 是其在地学中应用的一个新领域，为地球物理方法提供了新的思路。(NMR is a cutting-edge technology, medicine and other fields in physics and has more general application. The high-resolution non-destructive and are characterized by the biggest advantage of this technology. The use of NMR to come to learn that water is applied in a new area for geophysical methods to provide a new way of thinking.)
