摘要

为弥补传统无线网络在射频链路难以到达的地方信号接收困难的问题

采用了将光载无线通信（RoF）技术作为一种无线接入方式与正交频分复用（OFDM）无源光网络（PON）有线接入网络相结合的方式

提出了一种基于外调制法单边带（SSB）调制方式承载60 GHz毫米波结合反射式半导体光放大器（RSOA）的有线与无线结合的双向传输系统

并完成了平台的搭建。在此基础上完成了理论分析和实验验证

通过仿真软件Optisystem

对基于RSOA的双向有线及无线混合接入系统背靠背以及光纤传输20 km后的系统性能进行了仿真分析

结果表明:当发送信号采用正交振幅调制（QAM）

4QAM和16QAM两种信号采用SSB调制方式承载毫米波经光纤传输20 km后

接收端系统星座图旋转度和发散度最小

系统性能最好

满足系统传输性能要求。

Abstract

Considering the difficulty of receiving signals in traditional wireless networks where the radio frequency link is hard to reach

a method combining Radio over Fiber（RoF） technology as a wireless access mode with Orthogonal Frequency Division Multiplexing（OFDM） Passive Optical Network（PON） wired access network is adopted. An external modulation method based on Single Side Band（SSB） modulation mode is proposed to carry 60 GHz millimeter wave combined with reflective semiconductor light. The transmission platform is built combining wired and wireless two-way transmission based on Reflective Semiconductor Optical Amplifier（RSOA）. The theoretical analysis and experimental verification are completed based on this platform. Through simulation

the system performances of RSOA-based two-way wired and wireless hybrid access system are investigated at back-to-back and 20 km optical fiber transmission cases. The results show that when the transmitted signal adopts Quadrature Amplitude Modulation（QAM） formats

4 QAM and 16 QAM signals adopt SSB modulation technique to carry millimeter wave through optical fiber transmission show best performance after 20 km transmission

which can meet the requirement of the network.
