Title (EN) METHOD FOR TRANSMITTING A SPACE-FREQUENCY ENCODED DATA SIGNAL VIA A PLURALITY OF TRANSMITTING ENTITIES
(FR) PROCEDE DE TRANSMISSION D'UN SIGNAL DE DONNEES CODE ESPACE-FREQUENCE VIA UNE PLURALITE D'ENTITES D'EMISSION
Abstract:
(EN) The invention relates to a method for transmitting a data signal comprising a sequence of symbols to a receiver, said method including the generation of a plurality of OFDM signals respectively transmitted by a plurality of transmission entities (EEi). The method includes the following steps: • generating a plurality of a sequence of pairs of symbols, comprising the sub-steps of generating at least one pair of symbols that are orthogonal to an existing pair of symbols of the sequence of symbols, generating at least one pair of symbols by duplicating the existing pair of symbols, and allocating at least one existing pair, the at least one orthogonal pair of symbols, and the at least one duplicated pair of symbols to the transmission entities of the plurality of transmission entities, the sub-steps being repeated for all the pairs of symbols in said sequence of symbols; • generating the plurality of OFDM signals from the plurality of a sequence of pairs of symbols, the OFDM signals comprising a number of sub-carriers equal to twice the number of transmitting entities.
(FR) Procédé de transmission d'un signal de données comportant une suite de symboles à destination d'un récepteur, ledit procédé comportant la génération d'une pluralité de signaux OFDM émis respectivement par une pluralité d'entités d'émission (EEi). Le procédé comporte les étapes de : • génération d'une pluralité d'une succession de couples de symboles, comportant les sous-étapes de génération d'au moins un couple de symboles orthogonal à un couple courant de symboles de la suite de symboles, génération d'au moins un couple de symboles par duplication du couple courant de symboles, et allocation d'au moins un couple courant, du au moins un couple de symboles orthogonal et du au moins un couple de symboles dupliqué aux entités d'émission de la pluralité d'entités d'émission, les sous-étapes étant réitérées pour tous les couples de symboles de ladite suite de symboles, • génération de la pluralité de signaux OFDM à partir de la pluralité d'une succession de couples de symboles, les signaux OFDM comportant un nombre de sous-porteuses égal au double du nombre d'entités d'émission.
