基于多参数融合的超宽带基站布设优化方法
Optimization Method for Ultra-Wideband Base Station Configuration Based on Multi-Parameter Fusion
摘要
Abstract
Ultra-wideband indoor positioning accuracy is affected by Non-Line of Sight(NLOS),multipath effect,base station configuration and other factors,and these factors are related to the base station configuration.Therefore,this paper proposes a base station configuration optimization mathematical model based on positioning dilution of precision(PDOP),time difference of arrival(TDOA)measurement error and Cramer-Rao bound,which can be solved by intelligent algorithms such as genetic algorithm and firefly algorithm.Theoretical derivation and simulation test show that the opti-mized base station configuration has better average error and variance than the traditional cuboid 8 base station configura-tion.The experimental results in 14.5 m x 7.6 m x 3 m exhibition hall show that the positioning accuracy of the opti-mized base station configuration is improved by 0.713 2 cm,and the variance is reduced by 50.649 6 cm2,which has high stability.关键词
