如今毫米波通信和大规模MIMO、3D MIMO技术等成为移动通信领域的研究热点,对无线信号的传播预测要求更为精细。目前常用的室内信号无线传播模型有两种:经验模型和确定性模型。在3D MIMO场景下受到广泛关注的IEEE 802.11ad信道模型是根据信道测量得到的经验模型;而射线追踪模型则属于确定性模型。主要研究了IEEE 802.11ad信道模型和射线追踪模型,对两种模型进行了设计和实现,针对选定的室内场景分别使用IEEE 802.11ad信道模型和射线追踪模型进行仿真,并对仿真出来的数据进行统计,得到了到达时延、时延扩展、到达角、角度扩展参数的对比结果。仿真结果表明,两种信道模型都可以正确地对室内信道场景进行建模,但这两种模型还存在一定的差异。
Now millimeter wave communication and large scale MIMO
3D MIMO technology have become the research hotspot in the field of mobile communication. IEEE 802.11ad channel model
which is widely concerned in MIMO 3D scenario
is the empirical based on the measuring of the channel. However
ray tracing model belongs to the deterministic model. IEEE 802.11ad channel model and ray tracing channel model were introduced. Then the method of IEEE 802.11ad channel model and ray tracing channel model were simulated in the indoor scenes and the simulation data was counted that the comparison results of TOA
DS
AZIMUTH and AS were obtained. It turns out that both of the two channel models can be modeling for the indoor scenes correctly. But the two models also exist certain differences.
