室内长廊环境中毫米波传播特性仿真和分析

Simulation and Analysis of Millimeter-Wave Propagation Characteristics of Indoor Corridor Environment

基于入射及反弹射线法/镜像法对室内走廊环境的毫米波传播进行了仿真和分析,仿真结果与测量结果一致性良好,验证了该方法的正确性。同时分析了仿真中得到的接收功率、均方根时延扩展、波达方向、均方根角度扩展和多普勒频移等传播参数,为毫米波通信系统室内覆盖提供了依据。

In this paper, the millimeter-wave propagation characteristics of indoor corridor environment are simulated and analyzed using the method of SBR/IM （Shooting and bounding ray tracing/Image）. And it is agreed well by a comparison of simulated results and measured results, so the correctness of the method has been validated. Some propagation param- eters are obtained in the simulation, such as the indoor received power, RMS （ Root Mean Square） delay spread, direction of arrival, RMS angular spread, Doppler shift and so on. The contrast analysis of the above results provides the theoretical foundation for the indoor coverage of millimeter-wave communication system.
