Abstract: An apparatus and a corresponding method for mapping payload data of mapping input data streams onto a mapping output data stream having a channel bandwidth for transmission in a multi-carrier broadcast system includes first and second frame forming mechanisms. The first frame forming mechanism is adapted to form first frames having a first frame structure and the second frame forming mechanism is adapted to form second frames having a second frame structure. Preferably, in a second frame structure the data blocks of a particular mapping input data stream are spread in time and frequency over various data symbols and various data segments of the second frames to provide high robustness against disturbances. The payload portion of the second frame is preferably segmented into various data segments enabling use of a narrow-band receiver, even if both the first and second frames cover the same total channel bandwidth.

Abstract: In a MIMO communications system a first communications device applies beamforming to a complete transmission packet including both synchronization data and either payload data or training symbols. A second communications device evaluates the beamformed synchronization data and determines and transmits a feedback information indicating minimum required synchronization data and/or a minimum number of training symbols. The first communications device tailors the synchronization data and/or number of training symbols on the basis of the feedback information. Beamforming the complete transmission packet facilitates signal suppression at defined locations. When the channel properties change, the second communications device may provide further channel state information to adapt beamforming in the first communications device without transmission of not beamformed training symbols. The communications system may be a powerline telecommunications system.
