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 τ, specific to each transmitter. The method comprises at least one step of acquiring the approximate position of the terminal {circumflex over (p)}, the position pof a list of transmitters {Tx} in the vicinity of the terminal and the delays τassociated with them, a step of measuring pseudo-distances ρbetween the transmitters and the terminal and a step of associating the measurements ρwith the transmitters of known positions pby minimizing a cost function, said cost function ν(ρ,{circumflex over (p)},σ) corresponding to the norm of the error between the measurements ρand a model of measurements of the pseudo-distances applied to a permutation of the position of the transmitters σ.
