  • Frequency scheme for data transmission systems
    Publication number: 20040192316
    Abstract: A data transmission system contains at least two stations between which data bursts are exchanged via radio. A frequency hop is provided between the first channel mid-frequency which is used for the transmission and the second channel mid-frequency which is used for the feedback transmission, the height of the frequency hop corresponding to the intermediate frequency. Therefore, the local oscillators must not be tuned to new frequencies between the transmission and the feedback transmission.

  • Data transmission system, frame structure, and method for radio transmission of data
    Publication number: 20040105405
    Abstract: A data transmission system transmits first data bursts from a base station to mobile stations. The first data bursts at least in some cases contain two or more data blocks that are intended for different mobile stations. The data transmission system furthermore transmits second data bursts from at least one of the mobile stations to the base station and produces guard time intervals between successive data bursts.
