Abstract

The synchronisation system for TDM transmitters, supplying information to one or more reception stations, e.g. for a train control system, uses a receiver incorporated in each transmitters. Within each transmitter the transmission cycle for the other transmitters is compared with that for the transmitter itself and the transmission cycle is adapted if there is a difference between them. Pref. the transmission cycles in synchronism a out of synchronism with the correct transmission cycle are stored and the latter is altered if more are out of synchronism than in synchronism.
