Abstract

Un procédé de codage du type OFDM pour la communication de trames de données (Ti) sur un câble de communication filaire entre un émetteur et un récepteur pour une application aéronautique selon un spectre de communication, le spectre de communication comportant une pluralité de fréquences de communication prédéterminées (Fci), chaque trame (Ti) comportant un unique symbole pour une communication bas débit, le procédé comprenant une étape d’émission d’une pluralité de trames (Ti) de manière successive au cours du temps, chaque trame (Ti) comportant au moins une porteuse de pilotage fixe (PPF) ayant une fréquence fixe prédéterminée (Ff) et au moins une porteuse de pilotage variable (PPVi) ayant une fréquence variable entre des trames successives (Ti, Ti+1), la fréquence variable correspondant à une des fréquences de communication prédéterminées (Fci).
