Abstract
A method is proposed for generating an OFDM type multicarrier signal including OFDM blocks constituted by M carriers modulated by source symbols. The method includes the following steps: interleaving the M symbols of a block of source symbols into R sub-blocks of N interleaved symbols; obtaining a block of M time domain samples corresponding to the block of M source symbols; forming a peak vector containing N maximum amplitudes determined from among the M samples; attenuating the extrema of each sub-block of N time domain samples corresponding to the R sub-blocks of N interleaved symbols by a correction of symbols taking account of the peak vector and delivering R sub-blocks of N corrected interleaved symbols; de-interleaving the R sub-blocks of N corrected interleaved symbols delivering a block of M corrected source symbols; generating an OFDM block of the signals corresponding to the block of M corrected source symbols.
