The invention relates to a method of modulating a real data train grouped into blocks of nb.M real data, where M is the number of carriers and nb an integer greater than or equal to 2. According to the invention, the method comprises, for a block of real data: - a first modulation (21) by a first modulator of the first M/2 data, delivering a first set of modulated carriers; - a second modulation (22) by a second modulator of the following (nb-1).M data, delivering a second set of (nb-1).M modulated carriers; - a third modulation (23) by a third modulator of the last M/2 data, delivering a third set of modulated carriers; - a superposition (24) of the first, second and third sets, forming a block of OFDM/OQAM symbols of length nb.M/2, the first set being superposed with the start of the second set and the third set being superposed with the end of the second set. |
