OFDM全系统仿真代码，包括卷积编码，调制解调，四倍过采样-OFDM system-wide simulation code, including the convolution coding, modulation and demodulation, four times oversampling

MATLAB仿真OFDM过采样的东西，主要的星座图和每一个子载波上对应的星座图也被观察到。-MATLAB simulation OFDM sample things, the main constellation chart and each is the carrier of the corresponding constellation chart has been observed.
