提出了一种基于几何的适用于宽带多输入多输出(MIMO)移动端到移动端无线信道的随机散射模型.假设有效散射体位于三维(3D)双柱体的表面,将已有的窄带模型扩展到宽带并且把载频和带宽引入模型中,利用仿真实现信道,通过实现的信道矩阵进一步开展信道特征和参数研究,与现有的解析方法相比更加简单直接.通过对3D双柱体和二维双环散射模型的比较发现,3D模型对应的功率延迟分布的归一化功率和均方根时延扩展比二维的小,3D信道容量有一定的提升.
This paper proposes a geometry-based stochastic scattering model suitable for wideband multiple-input multiple-output (MIMO) mobile-to-mobile wireless channels.It is assumed that the effective scatterers are located on the surface of a three-dimensional (3D) Expand to broadband and introduce the carrier frequency and bandwidth into the model.Using the simulation to realize the channel and further study the channel characteristics and parameters through the realized channel matrix, The comparison of the two-dimensional double-loop scattering model shows that the normalized power and root mean square delay spread of the power delay distribution corresponding to the 3D model are smaller than the two-dimensional ones and the 3D channel capacity is improved to some extent.
