小区覆盖预测中一种有效的射线跟踪技术
An efficient ray-tracing method for propagation prediction in microcellular environment
-
摘要: 射线跟踪法是近年来常用于城市微小区和室内环境无线电波传播信道特性预测的方法,但其在具体实现方面仍有许多问题需要进一步的研究。本文将计算机图形学中的八叉树方法用于射线跟踪法,得到了一种提高射线跟踪效率的方法。

Abstract: Ray-tracing technique is an efficient method to analyse the propagation in urban and indoor environment, but there are still many questions which need to be studied while realizing. In this paper, octatree technique which was first used in computer graphics is used in ray-tracing, and the ray-tracing efficiency is improved. -
