    Multi-ray channel modeling for programmable wireless environments in the terahertz band by Wenyu LUO, Hechao LIU

    Published 2019-07-01
    “…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.…”
