Abstract

An AOA (Arrive of Angle) algorithm based on phase difference projection is proposed for the problem of inaccurate localization results of signal tags in indoor positioning. In terms of position localization accuracy, there is systematic error when performing AOA localization, and the area that can actually be localized with higher accuracy is small. Finally, the localization algorithm using AOA and RSSI (Received Signal Strength Indication) information fusion can effectively reduce the influence of multipath effect caused by indoor bad environment and improve the indoor localization accuracy. The proposed AOA and RSSI fusion algorithm is simulated and experimented, and the obtained experimental results show that the localization accuracy is effectively improved.
