Abstract

This paper concerns locational finding in broadband wireless networks in corporating OFDMA
technique at the plysical layer. In this regard, a novel estimation method is proposed to find the position of
active users. This method makes use of the power spectral density of the received signal from a specific user
to compare its likelihood to that of some reference points. Despite the conventional method which performs
well in a single path environment, the proposed method not only robusts in a muli-path environment, but also
it inherently incorporates path delay spreads to find the location of exiting users. Simulation results indicate
that the mean estimation error in the wimax network operation is around 11 meters at 3.5 Ghz with 5 Mhz
bandwidth and when reference points are 26.4 meters apart relying on SUI model.
