Patent ID: 8682341

Claim:
An apparatus for blind identification of single-frequency-network (SFN) transmitters which transmit virtually identical signals from multiple points of transmission, wherein broadcasts from the SFN transmitters are synchronized, comprising: an input module adapted to receive a plurality of pseudoranges, each determined by a receiver based on one of a plurality of wireless SFN signals transmitted at a predetermined frequency from a corresponding plurality of transmitters; a transmitter identification module adapted to identify one of the transmitters for each of the pseudoranges based the pseudoranges and a plurality of ranges each predetermined between one of the transmitters and one of a plurality of predetermined geographic locations; wherein the transmitter identification module comprises an error module adapted to generate an error for each of the geographic locations based on the ranges for the respective geographic locations and the pseudoranges, and wherein the transmitter identification module identifies the transmitters based on the errors.
