Abstract

For the problem of high communication overhead and greater algorithm complexity, this paper proposed a trajectory tracking method based on CSI signal in the tracking process of the indoor environment. Firstly, it extracted AOA spectrum which represented the CSI target position(angle) probability and obtained the Doppler shift by MUSIC algorithm and AOA spectrum to determine the moving speed and position of the person. Finally, it used the improved trilateral positioning centroid algorithm to locate personnel, simulated moving track to achieve accurate indoor tracking and locating personnel. By comparison with other algorithms and different speeds of movement of persons, simulation results show that the proposed method can greatly improve the accuracy and stability of positioning.
