141 GHz信号在植被中传播的测量和建模
Measurement and modeling of 141 GHz signal propagation in vegetation
摘要
Abstract
As a key enabling technology for 6G networks,terahertz(0.1–10 THz)communication is ex-pected to deliver terabit-per-second(Tbit/s)data rates.However,its practical deployment is hindered by unique propagation challenges,most notably severe signal attenuation caused by vegetation,which is starkly different from lower-frequency bands.Addressing this requires accurate channel modeling.This study presents channel measurements at the 141 GHz atmospheric window to investigate vegetation ef-fects on THz propagation.We employ two modeling approaches the VED model and a log-domain linear loss model based on extensive measurements using Syzygium buxifolium.Our results reveal that signal at-tenuation is strongly dependent on the vegetation's angle and horizontal position.Critically,we demon-strate that the channel statistics are best described by a heavy-tailed stable distribution,deviating from the conventional Rician or Weibull distributions.关键词
