摘　　要：根据电磁波传播的随机射线理论和渗流网格理论,得到Euclid距离和Manhattan距离度量下的二维随机网格信道中的路径损耗模型,式中参数具有明确的物理意义。使用此模型分析了视距和非视距情况下5.3GHz移动通信系统的功率分布特征。与实测数据进行比较,结果发现使用Euclid距离度量和Manhattan距离度量进行建模,所得的数值解与实际测量结果的均方误差在可以接受的范围内,证明了此模型的准确性和有效性。According to stochastic ray theory of radio propagation and percolation lattices theory, the path-loss models in 2D random lattice channels are analyzed based on Euclidean metric and Manhattan metric. Parameters of the model have clear and definite physical meanings. Finally, the model is applied to calculate the path-loss of mobile communications at 5.3GHz under the case of line-of-sight and non-line-of-sight. After comparison with the experimental data, the models both based on Euclidean metric and Manhattan metric can provide valuable results, which are in the domain of acceptance of accuracy. It proves that the models of no wave approach are effective and accurate.
