Abstract

Aiming at the problem of signal multipath and non-line-of-sight propagation in the indoor positioning environment, this paper proposes a residual correction and weighted least squares algorithm. Firstly, the multipath propagation signal is identified by the antenna array and the propagation path. Then, the arrival angle and the propagation distance of the two signals is obtained by the estimation algorithm.The simulation results show that the proposed algorithm can improve the accuracy of indoor positioning, and it has certain advantages in positioning time compared with other indoor localization algorithms.
