Abstract:
A synchronization method in a telecommunication system that includes a transmitting unit, a receiving unit and a transmission link between these two, the method comprising:transferring information to be transmitted in the telecommunication system from a transmitting unit to a receiving unit in a data frame that includes an information section and a synchronization section, wherein the bits of the synchronization section being in each consecutive data frame always in the same state as in a previous data frame,including in the synchronization section at least one synchronization bit in a selected logical state,mutually synchronizing the transmitting and receiving units of the data frame with synchronization bits, whereinforming a synchronization frame that includes at least as many synchronization bits as there are bits in the data frame, and the synchronization frame including bits in the same logical state as the data frame synchronization bits of the selected logical state, the number of the bits being no higher than the number of the data frame synchronization bits in the selected logical state, subtracted by one, wherein the other bits in the synchronization frame are in a complement state with regard to the selected logical state, andtransferring the synchronization frame over the transmission link to mutually synchronize the transmitting unit and the receiving unit.
