论文摘要
Terahertz（THZ）通信现在被视为第六代（6G）通信系统的可能技术之一。在本文中，提出了一种新型的三维（3D）时空非平稳的大规模多输入多输出（MIMO）通道模型，用于6G THZ室内通信系统。在基于几何的随机模型（GBSM）中，开发了时间，空间和频域中参数的初始化和演变，以生成完整的通道传输函数（CTF）。基于提出的模型，研究了相关函数，包括时间自动相关函数（ACF），空间互相关函数（CCF）和频率相关函数（FCF）。结果表明，仿真模型的统计特性与理论模型的统计特性非常匹配。模拟了不同频率的固定间隔。时间，空间和频域的非平稳性通过理论推导和仿真来验证。
Terahertz (THz) communication is now being considered as one of possible technologies for the sixth generation (6G) communication systems. In this paper, a novel three-dimensional (3D) space-time-frequency non-stationary massive multiple-input multiple-output (MIMO) channel model for 6G THz indoor communication systems is proposed. In this geometry-based stochastic model (GBSM), the initialization and evolution of parameters in time, space, and frequency domains are developed to generate the complete channel transfer function (CTF). Based on the proposed model, the correlation functions including time auto-correlation function (ACF), spatial crosscorrelation function (CCF), and frequency correlation function (FCF) are investigated. The results show that the statistical properties of the simulation model match well with those of the theoretical model. The stationary intervals at different frequencies are simulated. The non-stationarity in time, space, and frequency domains is verified by theoretical derivations and simulations.
