  • Patent number: 7089025
    Abstract: In a method for controlling radio systems designed for transmission/reception of signals based on at least two radio standards with different time patterns, with signals based on one of these radio standards being processed in each radio system, at least one synchronization signal is produced in the first and/or second radio system for synchronization, respectively, is transmitted to the respective other radio system and system information associated with that particular radio system is in each case stored in that radio system to which the synchronization signal is transmitted. The stored system information can be read by the respective other radio system via an interface, and times for transmission of signals can be calculated by means of the information which has been read. The transmission of signals or the production of events in a radio system can be enabled or inhibited by means of a signal from the other radio systems.

  • Patent number: 7062241
    Abstract: Only a single, standard-independent clock rate is generated in a signal processor or a signal processing structure, and correspondingly only precisely one clock frequency generator is then arranged on the chip. The signal processing path includes at least one controllable, asynchronous decimator for transposing the reception signals present in a uniform time frame into a respective standard-specific time frame. This enables signals of a variety of mobile phone standards to be processed.

  • Patent number: 7031677
    Abstract: An additional control voltage is used to adjust then operating point of a power amplifier. The amplitude of the control voltage is a measure of the maximum gain needed during the current time slot and which is already provided to the power amplifier before the beginning of the active time slot. This enables an individual adjustment of the operating point so that the power consumption can be reduced.

  • Publication number: 20060013324
    Abstract: The device for processing signals may be designed as a transmitting and receiving arrangement or exclusively as a receiving arrangement, and has a baseband component and a radiofrequency component. The interface between the baseband component and the radiofrequency component for the reception path is realized by an exclusively digital interface in the same way as the interface for the transmission path. The transmission of useful data—received useful data, useful data to be transmitted—is preferably effected via the digital interface completely separately from the transmission of the configuration data.

  • Publication number: 20060015640
    Abstract: A comparator unit is used to compare an actual transmission time signal with a nominal transmission time signal and to produce a difference signal from the discrepancy, from which difference signal a correction signal is produced in a control unit. This correction signal is used to control a correction unit, which compresses or extends an applied input data signal, thus changing the phase angle of the output data signal so as to minimize the discrepancy between the transmission times. The discrepancy is corrected independently of the system clock, and the correction speed is set variably.

  • Publication number: 20060013261
    Abstract: A radio station, in particular a mobile radio station, respectively has a unit for production of system information (2, 3), a memory unit (4, 5) and a control signal unit (6, 7) for production of control signals for the reception path and for the transmission path, for a reception path and for the transmission path. The two units (2, 3) for production of the system information are connected to a reference unit (1) by means of which reference system information is produced. The control signals for the reception path can be synchronized to the reference system information independently of the control signals for the transmission path, by programming a time discrepancy between the respective system information and the reference system information.

  • Publication number: 20050201503
    Abstract: To support a plurality of different mobile radio standards in mobile radio terminal devices using a single system oscillator, a sampling rate converter converts the sampling rates from an input rate to an output rate and additionally outputs control information which is suitable for operating signal processing components. The components receiving the control information are arranged in the signal flow upstream of the sampling rate converter, on average exactly at a virtual sampling frequency. The virtual sampling pattern is mapped onto the frame of the physical operating clock by simply gating out edges of the physical operating clock. Using the control signal, a clock control device generates a masked clock that has, on average, an edge repetition rate which corresponds to the virtual sampling frequency of the samples or to an integer multiple thereof.

  • Publication number: 20050058184
    Abstract: A discrete sampling control signal, which influences the sampling time, from a sampling phase selection element is calibrated by definition of quantization intervals for a sampling time error signal. For this purpose, a received signal is shifted through a series of time shifts ?i in the signal path upstream of the sampling phase selection element. The sampling time errors ei associated with the respective time shifts ?i are measured. The quantization steps of the sampling control signal that are suitable for the sampling phase selection element are then determined from the relationship obtained between ?i and ei.

  • Publication number: 20040102207
    Abstract: In mobile radio receivers, the transmission power must be raised before the start of the transmission process, and must be reduced again after the end of the transmission process. Until now, the transmission power has been controlled exclusively by varying the gain of the power amplifier. The inventive concept is based on using a scaling unit to additionally scale the amplitudes of the baseband signals in order to assist the switching-on and switching-off processes.

  • Publication number: 20040097250
    Abstract: A transmission configuration with a baseband module and a radio-frequency module is particularly suitable for transmission for mobile radio purposes. An interface which is designed on an exclusively digital basis is provided between the baseband module and the radio-frequency module and preferably ensures completely separate transmission of payload data and configuration data. The described principle allows the baseband module to be designed on a completely digital basis, and allows a high degree of flexibility by combination of a single baseband module with two or more different radio-frequency modules.
