摘　　要：毫米波的宽频带特性可以有效地解决高速宽带无线接入中面临的许多问题,是当下最具前景的短距离无线通信技术之一。文中基于入射及反弹射线法/镜像法对室内空房间的毫米波传播进行了仿真和分析,仿真结果与已知文献测量结果一致性良好。文中通过仿真得到接收功率和均方根时延扩展等传播参数,分析各种因素对接收功率的影响,该研究为以后简化室内毫米波传播模型提供了理论基础,有利于室内无线通信的网络规划与优化,为未来5G技术的发展奠定了基础。The wide band characteristics of millimeter wave can be applied for solving many problems on wide band wireless access, and it is considered as one of the most promising short distance wireless com- munication technologies. The radio propagation characteristics of indoor empty room environment are sim- ulated and analyzed using the method of shooting and bounding ray tracing/image （SBR/IM）. And it is agreed well by a comparison of simulated and measured results. Some propagation parameters are ob- tained in the simulation, such as the received power, root mean square delay spread and so on. Finally, the different effects of various factors on the received power are obtained. The study provides the theoreti- cal foundation to simplify for indoor millimeter wave propagation model and benefits the network planning and optimization of indoor wireless communication, thus it establishes the foundation for the development of 5G.
