Terahertz Channel Measurement Research and Analysis
Terahertz communication technology is one of the key technologies of the next generation wireless communication.Com-pared with the millimeter wave band of 5 G,the electromagnetic wave wavelength of the terahertz band is shorter,the beam is narrower,and the anti-capture ability and anti-interference ability are stronger.On the other hand,higher frequencies mean greater attenuation.In the terahertz band,the propagation distance is further shortened compared with millimeter wave,which requires the measurement and modeling of the wireless propagation environment in the terahertz band as the basis for evaluating the terahertz communication tech-nology.Rohde & Schwarz has rich research experience in channel measurement.In order to promote the research work of channel measurement in terahertz band,this paper introduces two methods of time-domain channel measurement and frequency-domain channel measurement in terahertz band.Channel measurement of common communication scenes such as city street canyons and indoor shopping centers in the 158 GHz and 300 GHz frequency bands was carried out,and the Channel Impulse Response(CIR)was ana-lyzed.Finally,it is pointed out that terahertz technology has a certain research basis in the academic field,but there are still many technical challenges to be solved.Through the introduction of channel measurement method and the analysis of measured results,chan-nel characteristics in the terahertz band are studied and summarized in this paper,which lays a foundation for subsequent research work in the field of terahertz.
