摘　　要：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.A geometry-based stochastic scattering model for wideband multi-input multi-output（ MIMO）mobile-to-mobile channels based on three dimensional（ 3D） two-cylinders was proposed. The proposed narrowband model is extended to wideband,and the carrier frequency and bandwidth was introduced into the model. The channel realization by using channel matrix is much more straight-forward and concise to study the channel characteristics compared with the too complicated analytical solutions available so far.The channel properties and parameters were further investigated based on the simulation model and realized channels. Simulations are compared with the two dimensional two-ring model. It can be found that the normalized power of power-delay-profile and root mean square delay spread of the proposed 3D model are smaller but the channel capacity are larger.
