| 51961 | 但实际基站部署并不是完全随机的， | However, the actual base station deployment is not completely random. |
| 51962 | 针对基站在空间上存在互斥的情况，文章采用泊松硬核过程(PHCP)建模异构蜂窝网络(HCN)， | In view of the mutual exclusion of base stations, we propose the Poisson Hard-Core Process(PHCP) to model the Homogeneous Cellular Network(HCN). |

| 51964 | 采用每层泊松SIR近似方法推导出了两层基于PHCP的HCN的近似覆盖率。 | Then per tier approximate SIR analysis based on PPP method is used to derive the approximate coverage of PHCP heterogeneous network. |
| 51965 | 仿真结果表明，该方法所产生的近似覆盖率为实际覆盖率的渐近下边界， | The simulation results show that the approximate coverage generated by this method is the lower bound of the actual coverage, |
