Research on Three - dimensional Location Based on Wireless Communication Base Station

Chan-Taylor-3 Dalgorithm,TOA,NLOS,TDOA

Abstract—This paper studies the problem of wireless communication base station indoor positioning of a three-dimensional, innovation of the Chan-Taylor-3D cooperative localization algorithm, and establish the corresponding model, can be very good in the NLOS environment, according to the measured values of TOA and the base station coordinates, calculate the corresponding TDOA, the Chan position calculation method of all terminals, to those obtained the terminal coordinate reconstruction of TOA, and then calculate the base station TDOA, two from the left had used the N-8 base stations, one of them as the reference base station, using the Taylor iterative method, three-dimensional coordinates of terminal. Repeat the above steps until the end of all the base stations, get a terminal coordinates, the final coordinates of each line will be calculated on average, as the final end of the final line of the line. The position of the terminal is solved, and the calculation error is analyzed, and the model is evaluated and prospected.
