摘　　要：为了能够在复杂的室内电磁环境下精确地对室内的无线发射机基站进行部署规划,本文软件仿真分析模块采用室内优势路径传播模型,该模型可以对仿真区域的电磁覆盖以及发射机和接收机之间的多径传播进行仿真。仿真结束后软件将仿真结果即室内仿真区域内各点的接收功率、电场强度以及各基站的载干比等以二维三维可视化的方式显示。结果表明,在复杂的室内环境下,室内优势路径传播模型比传统的射线追踪模型运算更加精确、仿真运行时间更短。An indoor electromagnetic simulation software is designed for accurately planning indoor wireless transmitter base stations in the complex indoor electromagnetic environment. The dominant path propagation model used in the simulation and analysis module can simulate electromagnetic coverage in the simulation area and multi-path propaga-tion between transmitter and receiver. The receive power, electric field intensity, and carrier-to-interference ratio of every base station, etc. can be got and displayed in 2D or 3D mode after the simulation. In the complex indoor envi-ronment, the accuracy of the indoor dominant path prediction model is better and the running time of simulation is shorter than traditional ray tracing model.
