摘要
本文介绍了一种在毫米波频段运行的基于几何的三维室内随机信道模型(GSCM),该模型模仿了智能手机中 5G 技术的使用以及室内环境中设备(包括物联网)之间的无线通信。该模型结合了散射体的三维反抛物线分布,可输出随机变量联合和边际概率密度函数(PDF)的精确闭式表达:接收器的到达时间(ToA)和到达角度(AoAs)。然后,通过在光线跟踪软件中对接收器的不同几何配置进行严格模拟,将模拟得到的 PDF 与模型理论计算得到的 PDF 进行比较,验证模型的新颖性和数学准确性。
3-D Geometric-Based Indoor Stochastic Modeling Using Inverse Parabolic Scatterer Distribution
This article presents a 3-D indoor, geometric-based, stochastic channel model (GSCM) operating in the mm-wave frequency band, imitating the use of 5G technology in smartphones and wireless communication among devices (including IoT) in an indoor environment. The model incorporates a 3-D inverse parabolic distribution of the scatterers to output exact closed-form expressions of the joint and marginal probability density functions (PDFs) of the random variables: time of arrival (ToA) and angles of arrival (AoAs) at the receiver. The model is then verified through rigorous simulations in ray-tracing software with different geometric configurations of the receiver, by comparing the PDFs obtained through simulations with the theoretically calculated PDFs from the model, to prove its novelty and mathematical accuracy.
