使用SAS工具基于实测数据的指纹定位算法研究
Research on Fingerprinting positioning techniques based on Drive Test data using SAS tools
移动互联网和定位服务LBS日益火爆,由于GPS定位有其局限之处,因此蜂窝基站定位更显重要。本文在对现有指纹定位算法的研究基础上,使用SAS统计分析工具,结合石家庄实际路测数据,首先建立指纹数据库,然后利用SAS工具的聚类分析与分类判别功能,从基于经纬度和基于单基站BCCHLevel两个方面对指纹定位进行了初步验证。结果表明指纹定位精度比传统RSS定位精度大大提高。文章最后在总结最新技术的基础上,本文列出了马尔科夫模型以及减小误差、调高性能、增加准确性相关的几个调优点。
With the fast growing of mobile Internet and LBS, GPS positioning has its limits, so cellular site positioning is becoming more and more important. Based on the study of the existing Fingerprint techniques, using the SAS statistical analysis tool, combined with the the Shijiazhuang drive test data, first create a fingerprint database, then use cluster analysis and classification discriminant function of SAS, perform a preliminary validation from two perspective--atitude and longitude and single base station BCCHLevel. Results show great promotion of precision comprared to the traditional RSS positioning. In the end, there're also suggestions about tuning the algorithms which includes Markov model, error diminishing, performance promoting, accuracy improvement.
