Abstract
A method for generating a multicarrier signal formed by multicarrier symbols. the method includes: obtaining N first modulating symbols and N second modulating symbols from a sequence of source symbols, the obtaining including, for at least one of the source symbols indexed k, a sub-step of: linearly combining a real part and an imaginary part respectively, of the symbol indexed k with a real part and an imaginary part respectively, of one of the source symbols indexed k+/−R, with R being a non-zero integer, delivering at least one first and one second combined symbol respectively; performing a frequency-time transformation of the N first and N second modulating symbols respectively, delivering a first block and a second block of N carriers respectively; and generating the multicarrier symbol from the first and second blocks of N carriers.
