摘要： 根据随机射线理论和渗流网格理论，对Manhattan距离下二维随机网格信道中的功率分布特性进行研究，得到计算平均接收功率的近似表达式，且式中参数具有明确的物理意义，与实测数据的比较也说明此模型的有效性。

Abstract: According to the stochastic ray theory and the percolation lattices theory, power distribution properties in 2D random lattice channels are analyzed based on the Manhattan metric. The approximate formulae under Manhattan metric are derived from rigorous mathematical derivation. Parameters in the formulae have clear physical meanings. Experimental data prove the efficiency of the model.
