Patent ID: 7535983

Claim:
A method for receiving data in a telecommunication system including at least one transmitter and one receiver, the transmitter being configured to transmit a signal formed by a pulse sequence including a number (Np) of pulses distributed over a number (Np) of time windows, each pulse being enclosed within a time chip having a position within a corresponding time window defined by a chip number, comprising: synchronizing, at the receiver, a received signal from the transmitter, the synchronizing including: scanning at the receiver the time windows, each having a same predetermined width, until a beginning of the pulse sequence is detected within one of the time windows, subdividing only the one of the time windows in which the beginning of the pulse sequence is detected into a plurality of sub-windows, each having a same sub-window width, scanning only the sub-windows until the beginning of the pulse sequence is detected within one of the sub-windows, and identifying the one of the sub-windows in which the beginning of the pulse sequence is detected as the beginning of the pulse sequence if the sub-window width in which the beginning of the pulse sequence is detected is smaller than a predetermined minimum width.
