Mobile Location Using Scatter Information in the NLOS Environment

Abstract

A NLOS(Non line of sight) high-resolution location algorithm has been brought forward based on TOA(Time of Arrival),AOA(Angle of Arrival),which can be measured by two base station. The algorithm bases on the single reflect model, and it reduces the number of the scatters needed in the algorithm from at least six in [1] to the three. The algorithm translates the NLOS error into the determinate factor by the single reflect model, so it can effectively mitigate the NLOS error. The simulation proves the algorithm validity in the NLOS scenarios.
