DYNAMIC INTERLEAVING METHOD AND DEVICE

摘要

The invention relates to an interleaving method (2) and a frequency interleaver (9) for interleaving data symbols. Said data symbols are assignable to carriers of the set of N_FFT carriers of the module for multiplexing and modulating by orthogonal functions of a multi-carrier transmission device (3). The inventive method consists in interleaving the block of successive Npm data symbols according to a time-varying interleaving law for a given transmission mode of the transmission device with Npm equal to or less than N_FFT.
