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.

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.

Abstract: A mobile station is provided comprising a transmission and reception unit and an identification module that can be inserted into the mobile station. The mobile station provides a user, in the standby mode, with services and/or data records that can be retrieved by the user. To prevent unauthorized access to the services and/or data records, each service and/or data record is assigned a characteristic access identifier that is activated or deactivated by inputting and/or transmitting an associated security code. For the purpose of inputting and/or transmitting the security code, the mobile station comprises a security component. Depending on the state of the access identifier, whether activated or deactivated, access to a service and/or data record in the standby mode on the mobile station is disabled or enabled, respectively.
