摘　　要：太赫兹(Terahertz, THz)通信是6G的关键技术之一。由于太赫兹技术具有大带宽和超高速率的特点,越来越受到关注。为支持太赫兹无线通信设备的性能评估,建立能够表征信道特性的无线信道模型至关重要。提出了一种基于散射特性的太赫兹信道模型,在室内场景中使用该信道模型生成信道系数和功率时延谱。分析结果表明,提出的信道模型能较好地表征太赫兹散射特性,能够支持太赫兹通信系统的设计与评估。Terahertz(THz)communication is one key technology of the 6G and is receiving more and more attention for its large bandwidth and ultra-high data rate features.To support performance evaluation of THz wireless communication devices,it is critical to model wireless channels that can characterize channel properties.In this paper,a THz channel model is proposed based on scattering characterization.The channel model is then applied to generate channel coefficients and Power Delay Profiles(PDP)in an indoor scenario.Evaluation results indicate that the proposed channel model can appropriately c haracterize THz scattering properties and support THz communication system design.
