A technique is provided that may be employed in multicarrier communications to improve the efficiency of error correction using symbol-oriented error correction methodologies, by reducing the number of error correction code symbols (102, 104...) that are received in error that result from a single channel error. More specifically, in this technique, bits from the symbols are allocated among the channels in such a way as to minimize the number of respective channels that are allocated bits belonging to more that one respective symbol during a respective transmission period.
L'invention porte sur une technique pouvant être mise en oeuvre dans des communications à ondes porteuses multiples pour améliorer l'efficacité de correction d'erreurs par des méthodologies de correction d'erreurs orientées symboles. Cette amélioration s'obtient par réduction du nombre des symboles de code (102, 104...) de correction d'erreurs reçus par erreur résultant d'une erreur de canal monovoie. Plus particulièrement, cette technique permet d'attribuer aux canaux des bits provenant des symboles, de manière à réduire au minimum le nombre de canaux respectifs auxquels sont affectés des bits appartenant à plus d'un symbole respectif au cours d'une période de transmission respective.
