ABSTRACT:
A method and a device for synchronizing data-transmission devices, in which devices a data signal is transmitted in the form of a stream of data bursts between a first station and a second station. A reference signal is transmitted in connection with the specific data burst. In a first step, a first reference signal is sent from the second station to the first station. In a second step, a channel estimation is carried out in the first station based on the reference signal received from the second station. In a third step, the first station sends to the second station a data burst predistorted on the basis of the channel estimation. In a fourth step, the first station sends to the second station a second reference signal altered on the basis of the channel estimation. In a fifth step, the second station synchronizes the data burst on the basis of the second reference signal.
