摘要/Abstract

摘要：

为了进一步提升当前主流太赫兹系统的通信容量，本文基于光子辅助太赫兹生成技术、波分复用（Wavelength Division Multiplexing，WDM）、多输入多输出技术（Multiple-Input Multiple-Output，MIMO）以及先进的数字信号处理，提出一种 $N × N$ MIMO光纤-无线-光纤融合太赫兹传输系统模型，搭建双信道WDM的 $2 × 2$ MIMO实验系统，并成功实现两路3 Gbaud四频相移键控（Quad-frequency Phase Shift Keying，QPSK）信号先后在10 km单模光纤（SMF-28）、3.8 m无线链路、2.2 km SMF-28上的传输，且误码率低于硬判决前向纠错（Hard-Decision Forward Error Correction，HD-FEC）的阈值 $3.8 × 10 - 3$ .

Abstract:

In order to further improve the communication capacity of the current mainstream terahertz system, based on photon-assisted terahertz generation technology, wavelength division multiplexing(WDM), multiple input multiple output technology(MIMO) and advanced digital signal processing, a model of $N × N$ MIMO fiber-wireless-fiber fusion terahertz transmission system is proposed. We built a dual-channel WDM $2 × 2$ MIMO experimental system, and successfully implemented two 3 Gbaud quad-frequency phase shift keying(QPSK) signal transmission over 10 km single-mode fiber(SMF-28), 3.8 m wireless link, 2.2 km SMF-28. The measured system error rate is lower than the hard-decision forward error correction(HD-FEC) threshold of $3.8 × 10 - 3$ .

Key words: terahertz, wavelength division multiplexing, multiple-input multiple-output technique, photonics-aid
