    摘要： Method of arranging a cellular radio network in a geographical area which is already covered by an existing cellular radio network, wherein cell clusters of the cellular radio network to be introduced and using a specific transmission frequency are located in areas determined by connecting at least two cells of the existing cellular radio network using the specific transmission frequency, and wherein the cell clusters are arranged such that they do not overlap with the cells of the existing cellular radio network. The cell clusters of the introduced cellular radio network may be adjusted by reducing the cell size of cell clusters of the introduced cellular radio network, and by introducing new cells into cell clusters of the introduced cellular radio network. The invention allows to reuse frequencies of an existing cellular radio network by an introduced cellular radio network in the same geographical area.

    摘要： MIMO transmission methods are applied to communicaiton systems in which a transmitter has more than one transmit antenna and a receiver has more than one receive antenna. Information to be transmitted is divided into a plurality of subsignals according to the number of used transmit antennas and each subsignal is processed separately before it is emitted by the respective transmit antenna. In the receiver the different receive signals are processed thus that subsignals are detected and decoded and the contribution of each detected and decoded subsignal is subtracted from the receive signals and whereby a feedback channel from receiver to transmitter is used to send control information to the transmitter depending on the receive situation. In order to optimize the usage of the MIMO channel the invention proposes the in the receiver the link quality of each subsignal is determined and information of each subsignal is transmitted to the receiver via the feedback channel and that in the transmitter properties of the subsignals are controlled by the link quality information.

    摘要： A method and an apparatus for determining the position and orientation of a mobile transmitter that has at least two linearly polarized antennas arranged at a predefined angle to one another. A plurality of receivers, which can be synchronized with the mobile transmitter and of which the position is known, each receive transmitter signals of predefined carrier frequency via a circularly polarized antenna. A field-theoretical model of the transmission path between the mobile transmitter and receivers is set up and defines the carrier phase measured values, the field-theoretical model is implemented in a Kalman filter, and the receiver signals are evaluated in terms of carrier phase measured values and/or time of arrival values. The position and orientation of the mobile transmitter are determined in the Kalman filter with use of the field-theoretical model and the carrier phase measured values and/or time of arrival values established from the receiver signals.

    摘要： Communication system for transmitting data packets via a plurality of virtual wireless communication links established between a base station and a plurality of operable mobile stations, the communication links having a variable transmission capacity and wherein messages for a requirement-oriented data transmission are transmitted on a plurality of communication links or channels within three types of control data packets. Said control data packets contain messages grouped according to their importance, allowing an efficient error treatment. The partitioning of messages into groups further allows an increase of the flexibility and efficiency of a data transmission, since only necessary control information is transmitted a direct decoding of received control data packets becomes possible without a detour via a higher level of a used communication model.
