对周围相邻的 8 邻居求和（元胞只有两种状态，0 或 1 ）。元胞也有一个单独的状态参量（所谓 记录 ）记录它们之前是否有非零状态的邻居。 在 0 与 1 之间产生一个随机数 r 。 如果总和> 0 （至少一个邻居）并且 r >阈值，或者元胞从未有过一个邻居，则元胞= 1 。 如果总和> 0 则设置"记录"的标志，记录这些元胞有一个非零的邻居。 (8 adjacent neighbors on the surrounding sum (cell only two states, 0 or 1). Cell also has a separate state parameters (so-called ' records' ) record that they have non-zero state before the neighbors. Between 0 and 1 generate a random number r. If the sum of> 0 (at least one neighbor) and r> threshold, or the cell has never had a neighbor, then cell = 1. If the sum> 0 set the " record" sign, record the cell has a non-zero neighbors.)

对实际降雨信道环境的模拟，根据不同的降雨概率，得到降雨的类型，以及降雨引起的路径损耗值。对于想要仿真实际环境和信道，可以加入降雨这一干扰，作为对性能评估的一个影响因素，其中涉及到的降雨类型及对应的雨衰减率依据国标。(Simulation of the actual channel environment rainfall, depending on the probability of rain, to get the type of precipitation, and the path loss value due to rainfall. For those who want the physical environment and channel emulation, you can add rain this interference as a factor for performance evaluation, which relates to the rainfall patterns and the corresponding rain attenuation rate based on the national standard.)
