基于三维射线跟踪的城市微小区电波传播预测算法

A Method Based on 3-D Ray Tracing for Propagation Prediction in Microcellular Environment

射线跟踪算法是用于城市微小区电波传播预测的一种有效算法 ,但大多文献只对其正向算法进行了详细的探讨 ,而对于比较精确的反向算法却少有提及 .本文对基于三维模型的射线跟踪反向算法进行了详细的讨论 。

Ray_tracing is an efficient method to analyze the propagation prediction in urban microcell.But most papers about this method only treat about the direct algorithms,only a few papers treat about the inverse algorithms.This paper discusses in detail the inverse algorithm based on ray_tracing method,and builds up a tracing model of municipal microcellular region.
