Positioning using mobile TV based on the DVB-SH standard

Abstract : Positioning in urban or indoor environments is a hot topic, due to both regulations such as the E911 and extension of location-based services targeting the mass market concentrated in metropolitan areas. In deep urban or indoor areas, it is generally recognized that satellite-based positioning systems are not suitable (alone) to provide a continuous, reliable, and accurate position to the user. Therefore, alternative positioning techniques may be useful to complement or replace satellite positioning in these environments. This paper investigates the possibility of using a mobile TV system based on the DVB-SH standard as a system of opportunity for positioning. A system-level modification is used in order to make emitter discrimination possible in the synchronized emitter network. Then, the signal processing steps required for pseudorange estimation are detailed. The proposed method is simulated using realistic channel sounding measurements and provides a mean positioning error around 40 m.
