Abstract

L'invention concerne un procédé d'émission d'un signal multiporteuse formé d'une succession temporelle de symboles constitués d'un ensemble d'éléments de données à valeurs réelles comprenant des éléments de données informatifs, et pour au moins certains desdits symboles, des pilotes. Selon l'invention, un tel procédé d'émission insère dans ledit signal multiporteuse au moins un préambule (21) formé d'au moins trois symboles consécutifs constitués de pilotes, dont au moins un symbole central constitué de pilotes dits centraux (23), tel que, pour chaque pilote central, les valeurs réelles des pilotes dudit préambule modulant une porteuse voisine dudit pilote central sont prises en compte lors d'une étape de détermination d'une interférence imaginaire affectant ledit pilote central, de façon que ledit préambule (21) permette de déterminer une estimation d'un canal de transmission entre un émetteur et ledit récepteur. Une modulation OFDM OQAM est utilisée.
