Abstract (en)

[origin: WO2014135811A1] The invention concerns a method for the multi-carrier transmission of a signal comprising OFDM blocks formed from N carriers modulated by a constellation symbol. According to the invention, the method comprises, for at least one OFDM block: - a phase (201) of prebuilding M prebuilt complex time samples representative of the N carriers of said OFDM block, and - a phase (202) of correcting the constellation symbols modulating the N carriers, comprising the following steps, repeated for each carrier: - detection (2021) of P samples having a power higher than a predefined threshold (a), delivering said P samples and M-P zero samples, forming M complex time samples to be corrected, - correcting (2022) the constellation symbol on the basis of said M complex time samples to be corrected, delivering an item of complex correction data (Fn), - building (2023) M complex time samples associated with said item of complex correction data, - updating (2024) said M prebuilt complex time samples.
