摘要 构建了强度调制直接检测光正交频分复用无源光网络(I M-DDO OFDM-PON)的VPI仿真系统,针对1024定点快速傅里叶变换(FFT)提出了基于统计特性的中间级输出字长优化映射表,通过VPI仿真验证了该映射表的准确性与正确性。 This paper constructs intensity modulation direct detection optical OFDM-PON （IMDD-OOFDM-PON） by VPI simulation system, it proposes stage-dependent minimum word length of 1024 point FFT basedon statistical property, and verifies the accuracy and correctness of the mapping table by VPI simulation.
