摘要
介绍了0.14THz超高速无线通信实验系统的主要组成部分和主要实验结果。从太赫兹电子学出发,基于太赫兹半导体器件和宽带数字调制解调技术,采用一种"低频段高速矢量调制+谐波混频+放大"的太赫兹高速信息传输技术路线,在国内首次成功实现了0.14THz 0.5km 10Gb/s高速信号实时传输和软件化事后解调,同时进行了4路高清视频信号的传输与解调。
This paper introduces main modules of 0.14 THz super high speed wireless communication experimental system and experimental results.The THz research group of Institute of Electronic Engineering of China Academy of Engineering Physics,from the view point of THz electronics,based on the THz semiconductor devices and wide band digital modulation and demodulation technologies,utilizing the technologies of ＂low frequency band hyper-speed vector modulation ＋ sub-harmonic mixer ＋ amplifier＂,successfully achieves 0.14 THz 0.5 km 10 Gb/s high speed transmission afterwards by means of soft demodulation,realizes 4 channel high-definition video signal real-time transmission and demodulation for the first time in China.
