Abstract

The invention relates to a method for the transmission of a multicarrier signal formed by a temporal succession of symbols consisting of a set of data elements with real values, including informative data elements, and pilots for at least some of said symbols. According to the invention, such a transmission method involves inserting at least one preamble (21) into the multicarrier signal, said preamble being formed from at least three consecutive symbols consisting of pilots, and at least one of the symbols of the preamble being a central symbol consisting of central pilots (23), such that, for each central pilot, the real values of the pilots of the preamble modulating a neighbouring carrier of the central pilot are taken into account during a step of determining an imaginary interference affecting the central pilot, in such a way that the preamble (21) enables an estimation of a transmission channel between a transmitter and the receiver to be determined. An OFDM OQAM modulation is used.
