    Indoor localization method based on CSI in complex environment by Xiaochao DANG, Xiong SI, Zhanjun HAO, Yaning HUANG, Yili HEI

    Published 2018-12-01
    “…Channel state information can provide more detailed sub-carrier information,which attracts the attention of researchers in indoor localization technology.In view of the shortcomings of the traditional indoor location method in the accuracy and stability of the complex indoor environment,an indoor localization method named ComLoc was proposed which could be applied to complex indoor environment,solved the influence of the multipath effect and noise interference on the positioning precision.The error of CSI signal was discussed,the sensitivity of CSI phase information to indoor environment was analyzed and the idea of trusted carrier link was proposed.By selecting reliable and stable link signal by phase difference,the misjudgment of position could be reduced.Based on many numerous experiments,the phase error of CSI was calibrated,and the characteristics of signal variation were extracted.The experimental results show that ComLoc is effective and efficient in the complex indoor environment.…”
