摘要

泊松点过程（PPP）由于其理论可分析性和随机性而被广泛用于无线网络建模及分析

但实际基站部署并不是完全随机的

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）

选择基于最大信干比（SIR）准则的基站接入方案

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。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

并且PHCP网络的覆盖率优于PPP网络覆盖率

更适应于具有互斥性的实际基站部署。

Abstract

The Poisson Point Process（PPP） is widely used in wireless network modeling and analysis due to its theoretical analytic and random nature. However

the actual base station deployment is not completely random. In view of the mutual exclusion of base stations

we propose the Poisson Hard-Core Process（PHCP） to model the Homogeneous Cellular Network（HCN）. We first choose a base station access scheme based on the Maximum Signal to Interference Ratio（SIR） criterion. Then per tier approximate SIR analysis based on PPP method is used to derive the approximate coverage of PHCP heterogeneous network. The simulation results show that the approximate coverage generated by this method is the lower bound of the actual coverage

and the coverage of the PHCP network is better than the PPP coverage

which is more suitable for the actual base station deployment with mutual exclusion.
