Ranging and Positioning Algorithm Based on DTMB System

Compared with Global Navigation Satellite System (GNSS) which has been widely applied, the systems based on digital terrestrial television broadcasting (DTTB) for positioning need to be further studied. In this paper, the localization algorithm based on digital television terrestrial multimedia broadcasting (DTMB) system is proposed. By utilizing the existing frame structure of DTMB system, the distance measurement and positioning methods are investigated in detail. The simulation experiments prove that the proposed scheme can provide accurate positioning results even under severe reception conditions. Index Terms-DTMB, pseudo-range measurement, positioning.
