Abstract

This paper gives an introduction to a generic OFDM based testbed for positioning using time difference of arrival (TDoA) measurements. An overview of the transmitter system and receiver system is given. Furthermore an inital access algorithm with interference mitigation for subsample delay estimation is presented and simulation results are shown. The influence of the geographic base station mapping and the used synchronization codes is discussed. First measurement results reveal perliminary figures for the expected performance leading to further algorithm investigations.
