说明：  OFDM里常用到的模型，一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模块，并统括系统性能的仿真验证了系统设计的可靠性。
(OFDM where commonly used to model a relatively complete OFDM communication system simulation design, including coding, modulation, IFFT, and down conversion, Gaussian channel model, the FFT, PAPR suppression, a variety of synchronization, demodulation and decoding module, and system including the system performance of the simulation to verify the reliability of the system design.)
