• It can be used in any complex environment , can locate all paths from transmitter to receiver which avoid redundant calculation , and it is a standard 3 - d forecast model ; in addition , it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently , the proagmme can back - search the virtual fountain tree when it is running . these operation increase the calculate speed and it result in the higher receive efficiency and precision . the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models . the comparsion result indicate the new model is a better model
  它可应用于任何复杂的传播环境中，能找到发射机到接收机之间的所有电波传播路径而无须冗余的计算，是一种准三维的预测模型；另外，从本质上讲，它仍然是一种基于镜像理论的点对点的射线跟踪法，所以它无须进行接收测试；而且由于采用了反向算法，运用数据结构中多叉树的概念，先确定需要计算的场点位置，找出所有能从源点到达场点的射线，并且可一次性建立一个虚拟源树，以后每次的计算只要通过对该树进行后序遍历即可，大大提高了运算速度，因而有较高的接收效率与精度。本文对该模型进行了相应的仿真，并将其预测结果与实测结果以及基于cost231经验性模型和基于强力射线跟踪确定性模型的预测结果进行了比较，结果表明了该模型的优越性。
