Both to sporadic as well as on continuous data communication aligned ofdm - transmission method for a wlan

摘要

In the case of the ofdm - based transmission method applies to the preamble (4, 7) of a data packet, that the n preamble - segments from the multiplication of a segment-type for all n preamble - segments fixed output segment with an n elements long multiplication sequence are. For the ofdm - data symbols, it is true that a plurality of temporally subsequently transmitted ofdm - symbols in each case at least a pilot signal, said pilot signal be transmitted in each case, the at least one subcarrier of the time index of the respective ofdm - symbol is dependent on.
