卡尔曼滤波在最小判别搜索定位系统中的应用
Application of Kalman filter in discriminant minimization search location symtem
摘要
Abstract
In order to improve location accuracy and fast positioning of wireless mobile equipment in the indoor environment, discriminant minimization search localization method based on fingerprint location is used,discriminant functions are de-signed to extract the spatial correlation of signal patterns,then the fine modified Newton’s method is used to find the mobile station.Considering the large variance of user’s location change and the influence of environmental noise,Kalman filter is introduced to discriminat minimization search localization method to improve positioning accuracy.The simulation results show that discriminant minimization search localization method combined with Kalman filter can achieve high location accu-racy and fast positioning in the indoor environment.关键词
