Generic OFDM with Cyclic Prefixing

C++,Fortran和Matlab分别实现的bp算法程序(The bp algorithm procedural C++, Fortran and Matlab achieve)

XFEM扩展有限元模拟二维裂纹动态扩展，由哈弗大学一个研究小组开发，非常值得学习(XFEM extended finite element simulations of two-dimensional crack dynamic propagation, developed by a team at Harvard University, is worth learning)

基于导频的信道估计，这个程序里主要实现了导频插入与提取(Pilot-based channel estimation, the program achieved a major pilot insertion and extraction)

说明：  使用matlab环境的GUI工具仿真八段均衡器，可视化界面，频域响应分析。(A case study of 8-band Equlizer in matlab by GUI tool)

根据不同的地理位置转化坐标的matlab源程序，给出注释，方便修改。(Depending on the geographic coordinate transformation matlab source, give comments, easy to modify.)

DAB发送端仿真，包括编码，删余，QPSK映射，频率交织，差分调制，循环嵌缀，加NULL、PRS,IFFT，信道(DAB sending end simulation, including coding, cut more than, QPSK mapping, interwoven frequency, differential modulation, the cycle is made up of inlay, plus NULL, PRS, IFFT, channel)

Harris Corner Detection Doc

说明：  配合使用可以实现基于循环平稳信号的盲源分离。使用JADE和SOBI算法。自己编的(BSS based on cyclostationarity)

This shows that relay power is an important criterion which decides the gain we get from simple relaying as compared to direct transmission.
