The invention relates to a method for transmitting a data signal comprising a sequence of symbols intended for a receiver, said method comprising the generation of a plurality of OFDM signals respectively transmitted by a plurality of transmission entities (EEi). The method includes the following steps: ° generating a plurality of a sequence of pairs of symbols, comprising the sub-steps of generating at least one pair of symbols that are orthogonal to an existing pair of symbols of the sequence of symbols, generating at least one pair of symbols by duplicating the existing pair of symbols, and allocating at least one existing pair, at least one orthogonal pair of symbols and at least one duplicated pair of symbols to the transmission entities of the plurality of transmission entities, the sub-steps being repeated for all the pairs of symbols in said sequence of symbols, ° generating the plurality of OFDM signals according to the plurality of a sequence of pairs of symbols, the OFDM signals comprising a number of sub-carriers equal to twice the number of transmitting entities. |
