摘要

针对当前准确定性信道模型不能准确地描

述室内场景亚太赫兹信道特性的问题，提出一种基于准确定性的亚太赫兹混合信道建模模型。首先，基于亚太赫兹信道多径稀疏簇特性，利用镜像法追踪视距径和低阶反射径建模确定性部分。其次，结合220 GHz室内大厅及132 GHz走廊场景测量数据，利用扩展的SV模型分别统计确定簇和随机簇内的散射径，对数正态分布描述簇内多径数分布，完成随机性部分建模。确定性信道冲激响应

Abstract

In response to the challenge posed by the limitations of traditional Quasi-Deterministic channel models in accurately characterizing the properties of indoor sub-THz channels

a Quasi-Deterministic hybrid channel modeling model for the sub-terahertz band was proposed. Firstly

considering the multipath sparse cluster characteristics of the sub-THz channel

the deterministic part was modeled by tracking the line-of-sight path and the low-order reflection path using the mirror method. Then

combining 220 GHz hall and 132 GHz corridor indoor scene measurements

using the extended SV (Saleh Valenzuela) model

the scattering paths within deterministic clusters and random clusters were separately counted

with a log-normal distribution describing the multipath distribution within clusters

thus completing the modeling of the stochastic component. The impulse response of the hybrid channel

was obtained by adding the deterministic channel impulse response

and the random channel impulse response

. Generally

the accuracy of the hybrid model was verified by Kolmogorov-Smirnov test

and its validity was confirmed by comparing the root-mean-square error and structural similarity indices of the small scale parameters of the extended SV model. The results demonstrate that the proposed model can accurately and effectively characterize the sub-THz channel.
