    摘要: 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.

    摘要: A circular buffer for a TDMA data transmission station temporarily stores digital transmit data occurring over a number of time slots in the transmission station and to be transmitted during a subsequent transmit time slot, and temporarily stores digital receive data received by the transmission station during a receive time slot and to be processed by it in a number of subsequent time slots. A TDMA data transmission station having a circular buffer is also provided.

    摘要: A hybrid satellite positioning receiver architecture is provided with a first receive path and a second receive path. The first receive path downconverts received satellite positioning signals of a first type to an intermediate frequency range, and the second receive path downconverts received satellite positioning signals of a second type to the same intermediate frequency range.

    摘要: 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.

    摘要: The invention relates to an apparatus and a method for ascertaining and correcting the optimum sampling time for an oversampled input bit stream. This involves feeding the data bit blanked with the current sampling phase into the comparative sequence and using the data bit to ascertain a new, corrected sampling phase. This decision-based approach enables the sampling phase to be continuously corrected.
