Abstract

We propose a novel approach in the context of multiple-input multiple-output communication systems to determine the position of mobile terminals based on estimated multipath signal parameters such as angle-of-arrival, angle-of-departure and delay-of-arrival using only one base station. This approach minimizes the errors occurring from the estimation of multipath parameters and gives the position of the mobile terminal by simultaneously resolving a set of algebraic location equations. The root-mean-square (RMS) errors are measured and compared with the Cramer-Rao lower bound to demonstrate the performance of the proposed method.
