Angle of Arrival Based Positioning Method in Single Frequency Networks

Broadcasting signals are considered as promising candidates for positioning and navigation needs thanks to its many advantages. However, most broadcasting networks are single frequency networks (SFN), in which the transmitter confusion problem poses a huge obstacle. Since all transmitters in a SFN broadcast the same signal simultaneously, the receiver cannot obtain the transmitter identities, thus can no longer determine its position. In this paper, a novel angle of arrival (AoA) based position method is proposed to realize positioning in SFN. The proposed method can overcome the transmitter confusion problem without modifications on the broadcasting sequences. Simulation results confirm that the proposed method can realize positioning in SFN with high accuracy.
