ABSTRACT:
A method and a system for synchronizing the coding and decoding of data during the transmission of and reception of the data, wherein after a start synchronization, correlations are carried out in several time slots of the received data stream with plural identical synchronizing signal sequences which are generated at the receiver and are displaced in time with respect to one another. By correlating one of these sequences with the identical synchronizing sequence which has been periodically inserted into the data stream at the transmitter, the state of synchronization is monitored and, if necessary, corrected. The invention combines the advantages of continuous synchronization with the rapid restoration of synchronization after disturbances in the transmission.
