Abstract
A method is provided for modulating a real data stream grouped into blocks of nb·M real data, where M is the number of carriers and nb is an integer greater than or equal to 2. The method includes, for a block of real data: a first modulation by a first modulator of the first M/2 data, delivering a first set of modulated carriers; a second modulation by a second modulator of the following (nb−1)·M data, delivering a second set of (nb−1)·M modulated carriers; a third modulation by a third modulator of the last M/2 data, delivering a third set of modulated carriers; and a superposition 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.
