摘要
太赫兹频段(0.1~10 THz)通信与传统无线通信相比,在高速数据传输、透射与成像方面、医疗成像和药物检测、物联网以及6G通信[1]等领域的独特优势,使其具有广阔的研究价值,有望推动通信技术的发展并在多个领域带来创新应用。但是太赫兹频段信号也具有弱穿透性、强大气层衰减、电路和天线设计复杂以及信号处理复杂的特性使其当前发展受限,针对此项,结合基于光子辅助的太赫兹技术和天线MIMO技术,通过分析基于光子辅助的太赫兹MIMO系统的研究现状、关键器件以及关键技术,展望了太赫兹通信未来可行的研究方向,以期为太赫兹频段信号的未来应用做出贡献。
Compared with traditional wireless communications,terahertz frequency band(0.1~10 THz)communications have unique advantages in high-speed data transmission,transmission and imaging,medical imaging and drug testing,Internet of Things,and 6G communications,making them of broad research value and expected to promote the development of communication technology and bring innovative applications in many fields.However,terahertz frequency band signals also have the characteristics of weak penetration,strong atmospheric attenuation,complex circuit and antenna design,and complex signal processing,which limits their current development.In view of this,this paper combines photon-assisted terahertz technology and antenna MIMO technology,analyzes the research status,key components,and key technologies of photon-assisted terahertz MIMO systems,and looks forward to the feasible research directions of terahertz communications in the future,in order to contribute to the future application of terahertz frequency band signals.
