摘要

提出了一种用于多单元多极化天线系统仿真的物理多输入多输出(MIMO)时空信道模型。该模型基于电磁(EM)散射，因此包含了实际中遇到的许多信道特性。通过引入任意物体散射的二元公式，得到了一个紧凑的通道表达式。模型中包含了信道和天线的极化特性，从而可以研究不同天线布置和极化的影响。给出了在微单元和皮单元场景下信道特性(如空间相关性、信道容量和时间演化)的仿真结果。

A physical MIMO radio channel model for multi-element multi-polarized antenna systems

A physical multi-input multi-output (MIMO) spatio-temporal channel model for simulation of multi-element multi-polarized antenna systems is presented. The model is based on electromagnetic (EM) scattering, hence including many of the channel characteristics encountered in practice. A compact channel expression is obtained by introducing a dyad formulation of the scattering from arbitrary objects. The polarization properties of the channel and the antennas are included in the model, thereby allowing studies of the impact of different antenna arrangements and polarizations. Simulation results are presented where channel properties such as spatial correlation, channel capacity, and time evolution are calculated for microcell and picocell scenarios.
