A novel hybrid model with dual-slope path loss is proposed to analyse the coverage probability for a given cell, and its coverage probability formula is derived by using a newly dual-slope path loss expression. A change of base station (BS) density may affect coverage probability obviously, yielding a low bound to simulation result of actual BSs. When the ratio of two path loss factor values is in a higher range, less BSs can achieve the same coverage probability. For the same SINR threshold and BS density, the coverage probability becomes higher under a lower range of path loss factor ratio.

基于双坡路损混合模型的下行覆盖分析

提出了一种具有双坡度路径损耗的新型混合 模型来分析给定小区的覆盖概率，并使用新的双坡度路径损耗表达式推导了其覆盖率公式。基站（BS）密度的变化可能会明显影响覆盖概率，从而对实际BS的仿真结果产生较低的限制。当两个路径损耗因子值的比率在较高范围内时，较少的BS可以实现相同的覆盖概率。对于相同的SINR阈值和BS密度，在路径损耗因子比率较低的范围内，覆盖概率会更高。
