摘要
在修正的入射及反弹射线法/镜像方法(SBR/IM)基础上提出一种改进方法,能准确地确定射线管与室内墙面的交点坐标。利用MATLAB语言设计了一个具有友好图形用户界面(GUI)的室内场强预测软件,同时给出程序中详尽的核心子模块。对室内微蜂窝电波传播的路径损耗进行了仿真,和已知文献测量结果对比,一致性良好。
In this paper,based on the method of the modified shooting-and-bounding ray/image method(SBR/IM),a novel approach is proposed.It can precisely determines the point of indoor intersection.The software of predicating indoor field strength with friendly GUI is designed using MATLAB language,and its kernel module is detailed.The path loss of indoor micorcell radio propagation is simulated.The results have shown good consistency with the known measured results from references.
