Zusammenfassung:	The disclosure relates to a method for generating preamble structures and signaling structures for a data signal in a MIMO-OFDM transmission system with a multitude of antennas. To this end, the preamble structure has, for each antenna, a synchronization section with a predetermined synchronization sequence and has a channel estimation section with a predetermined channel estimation sequence. The synchronization sequences fulfill equations (I) and (II). Alternatively, the channel estimation sequence can fulfill equation (III). This makes it possible to realize efficient and downlink compatible MIMO transmission systems.
