Abstract

We propose a simple and reconfigured dispersion-tolerant single sideband (SSB) orthogonal frequency division multiplexing (OFDM) radio over fiber (RoF) system enabled by digital signal processing (DSP), one in-phase/quadrature (I/Q) modulator and direct-detection. The generated radio frequency (RF) is based on DSP and the frequency can be flexibly adjusted, which can be employed in the future software-defined radio access network (RAN). Based on our proposed system, we have experimentally demonstrated 16-ary quadrature amplitude modulation (16QAM) 21.87-Gb/s 21-GHz and 38-GHz SSB-OFDM RoF signal generation and transmission over 80-km single-mode fiber (SMF), respectively.

摘要

我们提出了一种简单且重新配置的、由数字信号处理（DSP）、一个同相/正交（I/Q）调制器和直接检测实现的抗色散单边带（SSB）正交频分复用（OFDM）光纤无线（RoF）系统。生成的射频（RF）基于DSP，频率可灵活调整，可用于未来的软件定义无线接入网（RAN）。基于我们提出的系统，我们通过实验分别演示了16进制正交幅度调制（16QAM）21.87-Gb/s 21-GHz和38-GHz SSB-OFDM RoF信号在80公里单模光纤（SMF）上的生成和传输。
