射线跟踪算法应用综述

Overview of ray tracing algorithm application

随着5G网络的商用,运营商越来越关注5G网络部署的投资成本。在5G建网初期,运营商会通过网络规划工具对指定区域进行仿真,最后根据仿真结果制定有效的组网建设方案。由于射线跟踪算法能很好地对信号的直射、反射、衍射、透射等路径建模,它经常被用来作为精细化仿真的方法。本文介绍了射线跟踪相关研究进展及算法应用场景,通过实际案例,对两种射线跟踪算法进行研究,分析对比两种射线跟踪算法在5G规划仿真中的应用区别,验证两种算法的可靠性,为未来5G规划组网建设工作提供多种支撑方案。

With the commercial use of 5G network,operators pay more and more attention to the investment cost of 5G network deployment.In the initial stage of 5G network construction,the operator will simulate the designated area through the network planning tool,and finally formulate an effective network construction scheme according to the simulation results.Ray tracing algorithm is often used as a fi ne simulation method because it can well model the path of direct,refl ection,diffraction and transmission of signal.This paper introduces the research progress and algorithm application scenarios of ray tracing,studies two ray tracing algorithms through actual cases,analyzes and compares the application differences of the two ray tracing algorithms in 5G planning simulation,verifi es the reliability of the two algorithms,and provides a variety of support schemes for the future 5G planning network construction.
