说明：  OFDM系统是将一个用户的信息分别调制在了多个相互正交的子载波上面，对频率偏移非常敏感，OFDM同步技术非常关键，这里予以实现(OFDM system is a user' s information were prepared in a number of mutually orthogonal subcarriers above, is very sensitive to frequency offset, OFDM synchronization is critical to achieve here)

利用FFT变换，对sine2进行频谱分析，画出频谱图 利用iir源程序对输入波形sine2进行低通滤波，并将结果输出至result.dat。 (Using FFT transform, spectral analysis of sine2, draw the spectrum graph use the input waveform iir source sine2 to low-pass filtering, and the results output to result.dat.)

微带天线在已知谐振频率下的结构尺寸计算，以及其3D辐射方向图的展示，还有E面H面的辐射图展示。学习微带天线的同学可以参考~(Size of the microstrip antenna in the calculation of the known resonance frequency, radiation pattern, and its 3D display, and H-plane radiation pattern in E-plane display. Students can learn microstrip antenna reference ~)

利用MATLAB实时处理GPS数据,：利用MATLAB软件环境，现场接收并实时处理海上地球物理调查过程中的GPS定位数据，剔除原始数据中的跳点，处理定位误差.(Real-time GPS data processing, using MATLAB: using the MATLAB software environment, the site receives and real-time processing GPS positioning in the process of Marine geophysical survey data, eliminating hops in the raw data, processing positioning error.)

this is real fuzzy matlab code is hard2

分数阶傅里叶变换计算方面,使用大量的有限元法求解偏微分方程，是本科毕设的题目。( Fractional Fourier transform computing, Using a large number of finite element method to solve partial differential equations, The title of the commercial is undergraduate course yo.)

说明：  方程组追赶法的C++程序以及MATLAB源程序(Equations chase law procedures and the MATLAB C++ source code)
