Abstract
An interleaving method (1) and a frequency interleaver (EF) of data symbols. The data symbols are for allocation to carriers of a set of NFFT carriers of a module for multiplexing and modulation by orthogonal functions in a multicarrier transmitter device (EM). The method includes selecting in time-varying manner from the set of carriers, carriers that are dedicated to transmitting data symbols and in dynamically interleaving a block of carriers constituted by the selected carriers and by null carriers.
