Abstract

This paper demonstrates 300 GHz terahertz wireless communication using CMOS transmitter and receiver modules targeting beyond 5G (or 6G). In order to support OFDM, a self-heterodyne architecture is introduced, which effectively cancels inter-carrier-interference due to phase noise in multi-carrier modulation. Besides, to extend communication distance, the high-gain antenna of a 40 dBi Cassegrain antenna is designed. As a proof-of-concept, the paper successfully demonstrates real-time video transfer at a 10 m communication distance using 5G based OFDM at the 300 GHz frequency band.
面向6G实时视频传输的300 ghz波段自外差无线系统
本文演示了使用CMOS发射器和接收器模块的300 GHz太赫兹无线通信,目标是超过5G(或6G)。为了支持OFDM,引入了一种自外差结构,有效地消除了多载波调制中由于相位噪声引起的载波间干扰。此外,为了延长通信距离,设计了40 dBi卡塞格伦天线的高增益天线。作为概念验证,本文成功演示了在300 GHz频段使用基于5G的OFDM在10米通信距离上的实时视频传输。
