摘要

基于可编程无线环境的太赫兹通信系统允许针对不同无线设备以最适宜的方式进行电磁波传播的编程定制，不仅能够改善严重的衰落、干扰和非视距问题，还能显著提升系统的安全性和隐私性。针对可编程无线环境中太赫兹无线通信的信道建模问题，首先基于射线跟踪技术，结合视距、非视距的传播模型建立了太赫兹波段可编程无线环境的多射线信道模型。然后，在所建立传播模型的基础上，进一步研究了反射系数、注水功率分配策略下的宽带信道容量、均方根时延扩展等问题。实验仿真和分析结果表明，可编程无线环境通过对电磁波传输的主动干预，大大减轻了太赫兹室内无线传播中路径损耗和多径衰落的影响，提高了系统的传输容量。所提模型为后期太赫兹通信系统，尤其是室内太赫兹通信系统的设计提供了参考依据。

Abstract

Terahertz communication system based on programmable wireless environment allowed programming customization of electromagnetic wave propagation in the most suitable ways for different wireless devices.It could not only improve serious fading

interference and non-line-of-sight problems

but also significantly enhance the security and privacy of the system.The channel modeling of terahertz wireless communication in programmable wireless environment was focused.Firstly

a multi-ray channel model for terahertz-band programmable wireless environment was established based on ray tracing technology as well as the propagation model of line-of-sight and non-line-of-sight.Then

based on the established propagation model

reflection coefficient

the broadband channel capacity under the water-filling power allocation algorithm and the RMS delayed extension were further studied.The simulation and analysis results show that the programmable wireless environment greatly reduces the influence of path loss and multipath fading in terahertz wireless transmission through active interference in electromagnetic wave transmission

improves the transmission capacity of terahertz communication system

which provides a reference for the later design of terahertz communication system

especially indoor terahertz communication system.
