1. ) A method for transmitting data in a telecommunication system including at least one transceiver and one receiver, said transmitter being intended to transmit a signal formed by at least one sequence of Np pulses over Np time windows, each pulse being enclosed within a time chip whose position whithin its relevant time window is defined by a chip number, which method includes at least one signal synchronization step in the course of which at least one time window having a predermined width is scanned during a signal detection step in search of the beginning of a pulse sequence, said time window being then subdivided into a predefined number of sub-windows if the beginning of a pulse sequence has been detected within said time window, which sub-windows are then to be scanned during further signal detection steps in search of the beginning of said pulse sequence until such a beginning has been detected whithin one of said sub-windows which will then be substituted for the previous time window, until the width of the resulting sub-windows becomes smaller than a predetermined minimum width.
