Considering the influence of complex indoor environment and multi-path effects on the Wi Fi fingerprint positioning performance,this paper extracts channel state information( CSI) from the Intel 5300 wireless network card and utilizes the modified CSI amplitude and phase information as fingerprint features. A high-precision fingerprint database was built using the extreme gradient boosting( XGBoost) algorithm to achieve indoor positioning at a decimeter level. Experiments in the actual indoor environment ha...
