Abstract: This disclosure relates to controlled transmission of data in a data transmission system. Data from data interface elements may be transmitted in a controlled manner during the guard intervals or cyclic expansions of received RF signals. The received RF signals may be initially analyzed by a receiver to gather its characteristics. Based on the characteristics, the data interface elements are instructed to transfer the data during the guard intervals of the incoming RF signals.

Abstract: A diversity receiver includes a plurality of receiver circuits that are configured to receive and process the received radio frequency signals. A channel estimator is coupled to at least one of the plurality of receiver circuits and is configured to determine at least one channel estimation value for the received radio frequency signals. A controller is coupled to the channel estimator and to at least one of the plurality of receiver circuits and is configured to selectively activate or deactivate the at least one of the plurality of receiver circuits based on the determined at least one channel estimation value.

Abstract: A diversity receiver includes a plurality of antennas to receive radio frequency signals. A plurality of receiver circuits are each coupled to a respective one of the plurality of antennas to process the received radio frequency signals, and a channel estimator is coupled to at least one of the receiver circuits to determine at least one of channel estimation values for the received radio frequency signals.

Abstract: A radio receiver comprises a processing unit configured to subject a received radio signal to signal switching. A control unit is configured to output a control signal indicative of information related to the signal switching. A channel estimator is coupled to an output of the processing unit and configured to provide channel parameters based on the control signal received from the control unit.

Abstract: In a method for controlling the data flow on a radio link between a WLAN base station and a WLAN mobile station, the data rate on the radio link is reduced for in each case one time period (36, 37) at time intervals (35). One preferred field of application for the method is to restrict general or unauthorized transmission of a telephone call via the Internet.

Abstract: In a radio system for transmitting information channels A1, A2, A3 to radio receivers, the information channels A1, A2, A3 are transmitted in parallel over a number of data channels, each using different transmission standards. A radio receiver selects a transmission standard based on the type of its energy supply.

Abstract: A method for avoiding switch-over delays when changing channels in digital television transmission systems is based on a television transmission system in which a plurality of channels (K1, . . . , Kn) are transmitted in time-division-multiplexed fashion in a data stream (5). An overview channel comprising television picture information items from a plurality of the transmitted channels is provided at the transmitting end. The overview channel is decoded in the television receiver, and the picture information items of the selected channel that are provided in the overview channel are represented while changing channels.

Abstract: In an analog receiving section of a receiving device, the level of a received signal is adjusted by a first correction factor corresponding to a first digital level correction signal. Following this, the level-adjusted received signal is converted into a digital received signal. In a digital receiving section of the receiving device, the digital received signal is changed in accordance with a second digital level correction signal, in such a manner that a number of partial level adjustments are generated in successive time intervals in dependence on the level adjustment generated in the analog section. Thus, coarse level jumps produced in the analog receiving section can be split into individual small level jumps in the digital receiving section and stretched in time so that they can be processed in the subsequent demodulator.
