（1）通过Simulink创建仿真模型；（2）配置相关RTW（Real-Time Workshop）参数；（3）通过RTW（Real-Time Workshop）自动生成C代码文件，并理解主要文件、接口函数和变量的意义；（4）在Visual C++中将生成的C代码作适当修改，编译运行并分析结果。((1) created by Simulink simulation model (2) configuration related to RTW (Real-Time Workshop) parameters (3) RTW (Real-Time Workshop) automatically generate C code files, and understand the main document, interface functions and variables significance (4) Visual C++ generated C code will be modified as appropriate, compile, run and analyze the results.)

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)
