A general framework to investigate the interference and coverage probability is proposed in this paper for indoor terahertz (THz) communications with beamforming antennas. Due to the multipath effects of THz band (0.1–10 THz), the line of sight and non-line of sight interference from users and access points (APs) (both equipped with beamforming antennas) are separately analyzed based on distance-dependent probability functions. Moreover, to evaluate the effects of obstacles in real applications, a Poisson distribution blockage model is implemented. Moreover, the coverage probability is derived by means of signal to interference plus noise ratio (SINR). Numerical results are conducted to present the interference and coverage probability with different parameters, including the indoor area size, SINR threshold, numbers of interfering users and APs and half-power bandwidth of beamforming antenna.

使用波束赋形天线的室内太赫兹通信的干扰和覆盖范围建模

本文提出了一个用于研究与波束形成天线进行室内太赫兹（THz）通信的干扰和覆盖概率的通用框架。由于太赫兹频带（0.1–10太赫兹）的多径效应，基于距离相关的概率分别分析了来自用户和接入点（AP）（均装有波束成形天线）的视线和非视线干扰职能。此外，为了评估实际应用中障碍物的影响，实现了Poisson分布阻塞模型。此外，覆盖概率是通过信号干扰加噪声比（SINR）得出的。进行了数值结果，以显示不同参数的干扰和覆盖概率，包括室内区域大小，SINR阈值，
