仿真实现OFDM调制解调，在发射端，经串/并变换和IFFT变换，加上保护间隔（又称“循环前缀”），形成数字信号，通过信道到达接收端，结束端实现反变换，进行误码分析-Simulation OFDM demodulation, in the launch, the string of/and transform and IFFT transform, plus protection interval (also called "circulation prefix"), forming a digital signal, through the channel to the receiver, end realizing the transform, error analysis
