| Summary: | In order to solve the highly nonlinear nonconvex problem of the mathematical model in Bluetooth (angle of arrival (AOA)) localization, this paper proposes an alternating minimization algorithm for three-dimensional AOA localization. The algorithm method converts the solving error minimization solving three-dimensional coordinate problem in Bluetooth three-dimensional AOA localization model to solving four single-variable problems and alternately optimizes each variable to get the global optimal solution, which reduces the complexity of the model solving and achieves the high-precision localization performance without auxiliary information. The test is carried out in two states: dynamic line of sight (LOS) and static non–line of sight (NLOS), and the results show that the proposed method meets the demand for indoor positioning accuracy with a positioning error of 16 cm in LOS environment and 34 cm in NLOS environment. |
