Abstract (en)

[origin: WO2007028835A2] The invention relates to a method and device for modulating a signal comprising data symbols and reference symbols, which is characterised in that it comprises at least one step (3) involving the insertion of semi-pilot symbols that carry less information than the normally-used symbols but enough to obtain decisions made during a decoding step (9), said semi-pilot symbols being disposed between the data symbols and the reference symbols.
