METHOD AND DEVICE FOR DYNAMICALLY SELECTING ORTHOGONAL FUNCTIONS OF AN ORTHOGONAL TRANSMISSION SYSTEM

摘要

The invention relates to an interleaving method (1) and a data symbol frequency interleaver (EF). The data symbols are allocated to carriers of a set N_FF? of carriers of a multiplexing and modulating unit by means of orthogonal functions of a multicarrier transmission device (EM). The inventive method consists in selecting carriers used for transmitting data symbols from the carrier set in a time varying manner and in dynamically interleaving a block of carriers consisting of selected and zero carriers.
