摘要

通过对基于傅里叶变换过程的全光OFDM（正交频分复用）进行理论模型分析

采用马赫-曾德干涉仪级联的方式构造出复用/解复用模块

在光域上直接进行IDFT/DFT（离散型傅里叶逆变换/离散型傅里叶变换）过程。在DPSK（差分相移键控）调制、DQPSK（差分四相相移键控）调制、4QAM（2阶正交幅度调制）和16QAM（4阶正交幅度调制）下

利用全光复用/解复用模块模拟了8×40Gbit/s无保护间隔的OFDM系统传输

对误码率等性能作出分析。

Abstract

On the basis of the analysis of the theoretical model of Fourier transform-based all-optical OFDM

we construct a multiplexing/demultiplexing module by Mach-Zehnder interferometer cascading and directly carry out an IDFT/DFT process in the optical domain.Furthermore

with the modulation of DPSK

DQPSK

4QAM and 16QAM

we simulate 8×40 Gbit/s OFDM system transmission without GI by using the all-optical multiplexing/demultiplexing module and analyze its performances such as BER.
