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 application_number US 201113215356 A description fig1 and 2 have already been explained above with reference to the prior art fig3 illustrates a packet preamble based on the exemplary embodiment of the transmission method according to the invention as described in the following text the preamble is based on the preamble illustrated in fig1 for the wlan standard ieee 802 11a the packet preamble comprises a first part 4 with short segments time duration 0 4 u03bcs and a second part 7 with two longer segments time duration 3 2 u03bcs the first part 4 of the packet preamble contains n 18 short segments the segments which are annotated b or b each comprise a plurality of sample values the first part 4 of the preamble comprises a first section 5 and a second section 6 the total of 10 segments in the first section 5 are in this case identical the first section 5 in consequence behaves in the same way as the first part 1 of the preamble for the wlan standard ieee 802.
