一种用于移动系统场强预测的准三维射线跟踪模型

A quasi 3-D ray-tracing model for field prediction in mobile systems

提出了一种基于射线跟踪法的准三维模型。该模型可用于由任意形状建筑物和街道所组成的复杂微蜂窝区的场强预测 ,且具有计算效率和预测精度均高的优点。对该模型所得预测结果和实际测量结果进行了比较 。

A quasi 3 D model based on the ray tracing technique is presented. This model is applicable for field prediction with relatively high efficiency and accuracy in a complicated environment with arbitrarily shaped streets and buildings. A comparison between the calculated and measured results is made, which shows the effectiveness of this model.
