摘要
In an OFDM-based transmission method it can be stated for the preamble (4, 7) of a data packet that its N preamble segments (B, {overscore (B)}) are obtained from the segment-by-segment multiplication of an initial segment, which is fixed for all N preamble segments, by a multiplication sequence with a length of N elements. It can be stated for the OFDM data symbols that a plurality of OFDM symbols which are transmitted successively in time each include at least one pilot signal, with the respective subcarrier which transmits the at least one pilot signal being dependent on the time index of the espective OFDM symbol.
