中文摘要:
      为分析多层节点覆盖的异构蜂窝网络性能,采用独立的齐次泊松点过程分别对异构网络中的各层基站分 布进行了建模,选择最强信号干扰噪声比(SINR) 基站的接入方案,推导出多层异构蜂窝网络的覆盖概率,并且通 过仿真实验分析了影响整体网络覆盖概率的因素.实验结果表明: 多层异构网络在小基站密度和发射功率处于适 当值时有较好的覆盖率性能.
英文摘要:
      To analyze the performance of heterogeneous cellular network covered by multi-tier nodes, the paper deduces the coverage probability for multi-tier heterogeneous cellular network by using the independent homogeneous Poisson point process to model the distribution of each layer base stations in heterogeneous network and choosing the strongest signal to interference and noise ratio ( SINR) base station access scheme. Then the paper analyses the factors affecting the overall network coverage probability through simulation. The experimental results show that the multi-tier heterogeneous network has better coverage performance when the small base station density and thetransmit power are in proper value.
