Method for generating an OFDM multicarrier signal comprising OFDM blocks consisting of M carriers modulated by constellation symbols, called source symbols, a block of M source symbols corresponding to an OFDM block of M carriers, characterized in that it comprises, on the one hand: • a step of interleaving the M symbols of a block of source symbols into R sub-blocks of N interleaved symbols, where R, M and N are natural integers such that M=RxN; and, on the other hand, steps of: • obtaining a block of M temporal samples through a discrete Fourier transform on said block of M source symbols; • determining N maximum amplitudes out of said samples of said block of M temporal samples and forming a vector containing said N maximum amplitudes, called peak vector; and in that it also comprises steps of: • attenuating, by correcting constellation symbols, extrema of a sub-block of N temporal samples corresponding to the discrete Fourier transform on one of said R sub-blocks of N interleaved symbols, said correction taking into account at least said peak vector and delivering a sub-block of N corrected interleaved symbols, said attenuation step, which is repeated for each sub-block out of said R sub-blocks of N interleaved symbols, delivering R sub-blocks of N corrected interleaved symbols; • deinterleaving said R sub-blocks of N corrected interleaved symbols, delivering a block of M corrected source symbols; and • generating an OFDM block of said multicarrier signal through a discrete Fourier transform on said block of M corrected source symbols. characterized in that it comprises, on the one hand: • a step of interleaving the M symbols of a block of source symbols into R sub-blocks of N interleaved symbols, where R, M and N are natural integers such that M=RxN; • a step of interleaving the M symbols of a block of source symbols into R sub-blocks of N interleaved symbols, where R, M and N are natural integers such that M=RxN; and, on the other hand, steps of: • obtaining a block of M temporal samples through a discrete Fourier transform on said block of M source symbols; • determining N maximum amplitudes out of said samples of said block of M temporal samples and forming a vector containing said N maximum amplitudes, called peak vector; • obtaining a block of M temporal samples through a discrete Fourier transform on said block of M source symbols; • determining N maximum amplitudes out of said samples of said block of M temporal samples and forming a vector containing said N maximum amplitudes, called peak vector; and in that it also comprises steps of: • attenuating, by correcting constellation symbols, extrema of a sub-block of N temporal samples corresponding to the discrete Fourier transform on one of said R sub-blocks of N interleaved symbols, said correction taking into account at least said peak vector and delivering a sub-block of N corrected interleaved symbols, • attenuating, by correcting constellation symbols, extrema of a sub-block of N temporal samples corresponding to the discrete Fourier transform on one of said R sub-blocks of N interleaved symbols, said correction taking into account at least said peak vector and delivering a sub-block of N corrected interleaved symbols, said attenuation step, which is repeated for each sub-block out of said R sub-blocks of N interleaved symbols, delivering R sub-blocks of N corrected interleaved symbols; • deinterleaving said R sub-blocks of N corrected interleaved symbols, delivering a block of M corrected source symbols; and • generating an OFDM block of said multicarrier signal through a discrete Fourier transform on said block of M corrected source symbols. • deinterleaving said R sub-blocks of N corrected interleaved symbols, delivering a block of M corrected source symbols; and • generating an OFDM block of said multicarrier signal through a discrete Fourier transform on said block of M corrected source symbols.
