代码说明：

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)

Objective-C-Coding-Style-Guidelines
参考Apple Coding Guidelines for Cocoa, Google Objective-C Style Guide, Three20 Source Code Style Guildelines，并结合自己的实际情况总结了一份编码规范。自己在实行的过程中确实感觉到代码更加清晰了，看上去也“专业”了。希望对编码尚不规范的童鞋有所帮助。(Reference Apple Coding Guidelines for Cocoa, Google Objective-C Style Guide, Three20 Source Code Style Guildelines, and combined with their own summary of the actual situation of a coding standard. Themselves in the process of implementation of the code do feel more clear, and looked " professional" the. Coding not want to help regulate the children' s shoes.)
