标题： Measurement and Modeling on Terahertz Channel Propagation Through Vegetation

摘要： 太赫兹频段为高容量无线通信提供了有前景的机会，但面临着由植被引起的信道退化带来的重大挑战。 本文对通过植被的太赫兹信道传播进行了全面研究，提出了一种结合确定性植被依赖指数衰减建模与时间变化统计特征的混合建模方法。 通过使用绿萝进行广泛的实验室测量，我们发现植被引入了角度相关的功率损耗，信道统计遵循重尾稳定分布，而不是传统的瑞利或威布尔模型。 我们的户外测量在密集和稀疏的丁香花场景中揭示了衰减的显著季节性变化和高度相关效应，同时验证了VED模型在不同高度下保持与测量数据的良好一致性以及参数稳定性。 关键的误比特率分析揭示了在性能表现出由于重尾衰落导致的振荡行为的SNR阈值，这对实际太赫兹通信系统中的调制方案选择和功率控制策略具有重要意义。 显示英文摘要

摘要： The terahertz band offers promising opportunities for high-capacity wireless communications but faces significant challenges from vegetation-induced channel impairments. This article presents a comprehensive investigation of THz channel propagation through vegetation, introducing a hybrid modeling approach that combines deterministic vegetation dependent exponential decay modeling with statistical characterization of temporal variations. Through extensive laboratory measurements using Epipremnum aureum, we find that vegetation introduces angular-dependent power losses, with channel statistics following heavy tailed Stable distributions rather than conventional Rician or Weibull models. Our outdoor measurements with dense and sparse lilac scenarios reveal pronounced seasonal variations in attenuation and height-dependent effects, while validating the VED model's ability to maintain excellent agreement with measured data and parameter stability across different heights. Critical bit error rate analysis uncovers distinct SNR thresholds beyond which performance exhibits oscillatory behavior due to heavy-tailed fading, with significant implications for modulation scheme selection and power control strategies in practical THz communication systems.
