说明：  数学建模中的图论知识来研究最短路径的问题，利用Dijkstra算法matlab实现(Graph theory knowledge in mathematical modeling is used to study the shortest path problem, which is realized by using Dijkstra algorithm matlab.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

说明：  matlab教程，希望大家一起来学习，我看多好几遍了，非常不错。(matlab tutorial I hope everyone will work together to learn, I can see how good a few times, and very good.)

ST分段控制的iOS，精选ios编程学习源码，很好的参考资料。(ST segment control of iOS, ios programming learning source selection, a good reference.)

itools程序源码，可以管理IOS程序，需要Xcode编译，并生成MAC程序(itools can manage IOS program)
