Abstract (en)
[origin: WO2006035070A1] The invention relates to a method for realizing a link adaptation in a MIMO-OFDM transmisssion system during which a postamble structure (P1) is immediately attached to a data block (CTS) that does not contain sufficient information with regard to channel identification. This postamble structure has, for each antenna, a channel estimation section with a channel estimation sequence. A transmission mode in a respective station is selected on the basis of the received channel sequence.
