摘要:
A transmitting/receiving arrangement comprises a baseband module (1) and a radio-frequency module (3), which are connected to one another via a bidirectional data line (21) and a bit clock line (22) of a digital interface (2). In order to eliminate the influence of delay loops during the transmission of data in the opposite direction to the bit clock either the data bits are transmitted repeatedly or a bit clock frequency is set which is lower than the bit clock frequency for rectified transmission of bit clock signal and data signal.
摘要:
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.

摘要:
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.

摘要:
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.
摘要:
The invention relates to a transmitting and receiving arrangement for radios having a baseband component and a radio-frequency component that are connected via an interface for interchanging payload data. The interface includes a bidirectional data link that can be operated in a half-duplex mode for transmission of digital payload data to be transmitted from the baseband component to the radio-frequency component and for transmission of received digital payload data from the radio-frequency component to the baseband component.
摘要:
An arrangement and a method for synchronizing a signal processing apparatus with a received signal which has a characteristic signal content are disclosed. The arrangement has a first control loop which readjusts the signal processing apparatus with respect to the characteristic signal content on a content basis, and a second control loop which readjusts a flow control device in the signal processing apparatus with respect to the times at which the characteristic signal content appears, the first control loop and the second control loop being coupled such that a unique association is achieved between the position of the characteristic signal content in the received signal and the associated appearance time.

The present invention provides an arrangement and a method for synchronizing a signal processing apparatus with a received signal which has a characteristic signal content. The arrangement has a first control loop (1, 20, 3, 4), which readjusts the signal processing apparatus with respect to the characteristic signal content on a content basis, and a second control loop (1, 21, 3, 4), which readjusts a flow control device (4) in the signal processing apparatus with respect to the times at which the characteristic signal content appears, the first control loop (1, 20, 3, 4) and the second control loop (1, 21, 3, 4) being coupled such that a unique association is achieved between the position of the characteristic signal content in the received signal and the associated appearance time.
