  • Patent number: 7809393
    Abstract: A method for setting the transmitted power of a mobile communication device, particularly for a UMTS, involves setting a transmitted power with great accuracy and a good signal-to-noise ratio. The difference between a measurement of the transmitted power of the signal that is applied to the output antenna and a desired value for transmitted power according to power commands from the base station is used to produce the desired transmitted power.

  • Publication number: 20080200199
    Abstract: In a method for setting the transmitted power of a mobile communication device, particularly for a UMTS, a transmitted power that is being asked for at the time is to be set with great accuracy and a good signal-to-noise ratio. The digital signals I, A difference between a measurement of the transmitted power of the signal that is applied to the output antenna (7) and a sequel that is a desired value for transmitted power according to power commands from the base station (12), in such a way that they together produce the desired transmitted power.

  • Patent number: 7095815
    Abstract: The invention relates to a receiver and a method for initial synchronization of a receiver with the carrier frequency of a desired channel. It can happen during synchronization that the locally generated frequency van indeed be generated correctly although a divider ratio of a variable frequency divider inside the receiver and the reference frequency of a reference oscillator inside the receiver are simultaneously incorrectly set. The incorrect setting is evident in a particularly large skew which is detected in the receiver. In order to avoid such faulty settings even when use is made of budget-priced reference oscillators with relatively large frequency deviations, the skew is evaluated in the receiver and, should a prescribed threshold value be exceeded, a second and a third control signal are generated in order to correct the divider ratio and the reference frequency.

It can happen during synchronization that the locally generated frequency can indeed be generated correctly although a divider ratio of a variable frequency divider inside the receiver and the reference frequency of a reference oscillator 3 inside the receiver are simultaneously incorrectly set. The incorrect setting is evident in a particularly large skew which is detected in the receiver. In order to avoid such faulty settings even when use is made of budget-priced reference oscillators with relatively large frequency deviations, the skew is evaluated in the receiver and, should a prescribed threshold value be exceeded, a second and a third control signal are generated in order to correct the divider ratio and the reference frequency.

  • Publication number: 20010023184
    Abstract: In receiving devices for mobile communication comprising at least one controller, an improvement of the power saving is proposed for the evaluation of paging messages divided over a plurality of paging message sub-blocks and for setting the receiving device to a power-saving mode when the paging message does not contain a predefined subscriber identity number, in that the controller compares a received paging message sub-block with a stored sample and suppresses the reception of further paging message sub-blocks of the same paging message block when the received paging message sub-block matches.

  • Patent number: 5864804
    Abstract: The invention relates to a voice recognition system which is robust to echoes and other background noise. An additional input signal describing a disturbance is evaluated such that during this additional recognition there is maximum suppression of information contained in the input signal. For this purpose, comparison vectors are formed which are continuously adapted to the instantaneous interference. The voice recognition system receives speech signals superimposed by noise signals. Additionally, a first spectral analysis unit produces first spectral values combined to first spectral vectors derived from disturbed speech signals. Estimates of the noise signals are also produced. A second spectral analysis unit produces second spectral values combined to second spectral vectors from the noise signal estimates.
