摘要
为解决传统Cell-ID定位仅利用单基站进行定位且定位精确度不高的缺点。文章在传统Cell-ID定位的基础上,提出了基于分区加权Voronoi图的手机基站定位方式。同时,针对传统分区加权Voronoi图算法无法显示多扇区重叠的区域,对离散生成算法进行适当的改进,来突出多个生成元重叠的区域,即基站的重复覆盖区域。同时通过实验分析了基站数量、覆盖范围和功率对定位精确度的影响。
In order to solve the problem that the traditional Cell-ID positioning is based on single base station and the positioning accuracy is not high.Based on the traditional Cell-ID location,this paper proposes a mobile phone base station based on Partitioned Weighted Voronoi graph.At the same time,for the traditional Partitioned Weighted Voronoi graph algorithm can not show multi-sector overlap area,the discrete generation algorithm to make appropriate improvements to highlight a number of generating elements overlap area,that is,the overlapping area of the base station.The influence of the number,coverage and power of the base stations on the positioning accuracy is analyzed experimentally.
