Abstract |
In this paper a two step method based on Gauss-
Newton and factor graphs algorithm is proposed for
localization to enhance accuracy of localization. The
Gauss-Newton algorithm is accurate method for
positioning. The most important challenge of this
method is senility to initial point; this problem is
solved in positioning based on factor graphs. So, in
this paper, first positioning equations using angle of
arrival is considered based on factor graphs
algorithm. Second, final location estimation is
performed using Gauss Newton algorithm with error
near to Cramer-Rao bound. Simulation results shows
that positioning error using two step method has
maximum 6% gap to Cramer-Rao Bound. |
