论文摘要
在本文中，提出了多频的多键三维（3D）非平稳宽带多输入多输出（MIMO）通道模型。在每个单链接和不同频率的参数初始化中，考虑了空间一致性和多频相关性，包括大型参数（LSP）和小规模参数（SSP）。此外，当散射器和接收器（RX）移动时，SSP是时间变化的，并且更新。集群的时间演变是由出生和死亡过程建模的。考虑到相互关系的单连接通道模型可以很容易地扩展到多链接通道模型。研究了统计特性，包括空间互相关函数（CCF），功率延迟曲线（PDP）和相关矩阵共线性（CMC），并与第三代合作伙伴项目（3GPP）TR 38.901和Quasi确定性无线电通道生成器（Quadriga）通道模型进行了比较。此外，CCF通过测量数据进行了验证。
In this paper, a multi-frequency multi-link three-dimensional (3D) non-stationary wideband multiple-input multiple-output (MIMO) channel model is proposed. The spatial consistency and multi-frequency correlation are considered in parameters initialization of every single-link and different frequencies, including large scale parameters (LSPs) and small scale parameters (SSPs). Moreover, SSPs are time-variant and updated when scatterers and the receiver (Rx) are moving. The temporal evolution of clusters is modeled by birth and death processes. The single-link channel model which has considered the inter-correlation can be easily extended to multi-link channel model. Statistical properties, including spatial cross-correlation function (CCF), power delay profile (PDP), and correlation matrix collinearity (CMC) are investigated and compared with the 3rd generation partner project (3GPP) TR 38.901 and quasi deterministic radio channel generator (QuaDRiGa) channel models. Besides, the CCF is validated against measurement data.
