摘要： A method of transmitting data symbols via Orthogonal Frequency Division Multiplexed (OFDM) symbols, that includes forming data symbols into pairs, generating a first pair of modulation symbols for each of the pairs of data symbols, forming a first version of the OFDM symbols by modulating the sub-carriers allocated for carrying the data with the first and second modulation symbols, and modulating the one or more pilot carriers of the first version of the OFDM symbol. The method also includes generating a second pair of modulation symbols for each of the pairs of data symbols, forming a second version of the OFDM symbol by modulating the sub-carriers allocated for carrying the data with the third and fourth modulation symbols, modulating the one or more pilot carriers of the second version of the OFDM symbols and transmitting the first version of the OFDM symbol, and the second version of the OFDM symbol.

摘要： In an automatic gain control unit, the gain of a voltage-controlled amplifier (VCA) (25) is regulated with a closed-loop control circuit. The time constant of the control circuit is varied dependent on the magnitude (31) of the VCA output signal. As long as the magnitude (31) of the VCA output signal is small, the gain is slowly adjusted. In case the magnitude (31) of the VCA becomes so large that saturation of the analog-digital converter (28) might occur, the time constant of the control circuit is decreased, in order to allow for a quick adjustment of the amplifier's gain.

摘要： In digital broadcast systems, it is common to broadcast besides main services additional services like news services. Typically, these additional services are regularly updated and broadcasted by a service provider (3) several times a day. In order to keep service data transmitted by the additional services up to date in a receiving device (1) receiving the services, a method of accessing services is given according to which a respective service information about the services provided by service providers (3) is extracted from a service presently received by the receiving device (1), and then at least one of the services about which service information was extracted according to the respective extracted service information might be accessed. Thus, the service data can automatically be updated by the receiving device (1) itself, even if transmission conditions of an additional service like update rates change over the time.

摘要： A power line communication modem includes a receiver that receives a noise signal over a power line channel. The signal is OFDM-modulated on a set of sub-carriers, the sub-carriers being separated by a frequency separation. The power line communication modem also includes a processor that identifies a presence of a radio service within one or more fine frequency bands with a first resolution bandwidth by analyzing a plurality of fine frequency bands. The first resolution bandwidth is smaller than the frequency separation. The power line communication modem additionally includes a transmitter that excludes a signal in at least one of the plurality of fine frequency bands, in which the presence of the radio service has been identified, before transmitting the excluded signal.
