Abstract
A method for identifying transmitters by a terminal in a single-frequency network comprising a plurality of transmitters. The transmitters are synchronized and transmit with an artificial delay τi, specific to each transmitter. The method comprises at least one step of acquiring the approximate position of the terminal {circumflex over (p)}, the position pi of a list of transmitters {Tx} in the vicinity of the terminal and the delays τi associated with them, a step of measuring pseudo-distances ρi between the transmitters and the terminal and a step of associating the measurements ρi with the transmitters of known positions pi by minimizing a cost function, said cost function ν(ρi,{circumflex over (p)},σ) corresponding to the norm of the error between the measurements ρi and a model of measurements of the pseudo-distances applied to a permutation of the position of the transmitters σ.
