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.

Abstract: A method for receiving radio signals in a mobile station, and a mobile station for sending and receiving radio signals are proposed. The method and the mobile station have the aim of correcting predistorted code-spread and phase-modulated radio signals with respect to a phase error. In this context, in the receiver of the mobile station, the phase is determined for the radio signals, in order to carry out a phase demodulation, and the phases are mapped in a preselected phase zone and averaged, in order to formulate therefrom a phase correction factor, by which the code-despread radio signals are multiplied in order to correct the phase error. The method according to the present invention therefore improves the data detection of the received radio signals.

Abstract: A detection method in which a CDMA-coded data signal is transmitted in the form of a data stream of spread data bursts between a transmitter and a receiver, hierarchical CDMA codes being used for the transmission. In a first step, codes having a smaller spreading factor than a maximally to be detected spreading factor are detected. In a second step, codes having a larger spreading factor than in the previous step are detected, the detection results of the first step being taken into account. In a third step, the detection process is broken off if all codes are detected, or otherwise the second step is repeated with the detection results last obtained in each instance, until all codes are detected.
