Title (EN) METHOD FOR TRANSMITTING/RECEIVING SIGNAL HAVING SPREAD TRAINING SYMBOL IN MOBILE COMMUNICATION SYSTEM
(FR) PROCEDE POUR ENVOYER/RECEVOIR UN SIGNAL COMPORTANT UN SYMBOLE D'ENTRAINEMENT ETALE DANS UN SYSTEME DE COMMUNICATION
Abstract:
(EN) A method for transmitting/receiving signals in a mobile communication system, a pilot configuration of a mobile communication system capable of transmitting much more data using a conventional pilot signal, a channel estimation method, and a receiving method are disclosed. A method for transmitting a signal equipped with a training symbol in a mobile communication system which includes a transmission end capable of transmitting an output signal equipped with a training symbol for channel estimation of a reception end, includes the steps of: a) adding training symbols having the same amplitude to data symbols transmitted via subcarriers, and calculating the output signal transmitted via the subcarriers; and b) transmitting the calculated output signal via the subcarriers.
(FR) L'invention concerne un procédé pour envoyer/recevoir des signaux dans un système de communication mobile, une configuration pilote d'un système de communication mobile pouvant envoyer beaucoup plus de données à l'aide d'une onde pilote traditionnelle, un procédé d'évaluation de canal, ainsi qu'un procédé de réception. Cette invention concerne également un procédé pour émettre un signal comportant un symbole d'entraînement dans un système de communication mobile qui comprend une extrémité d'émission pouvant envoyer un signal de sortie comportant un symbole d'entraînement pour permettre une évaluation de canal d'une extrémité de réception. Ce procédé comprend les étapes qui consistent : a) à ajouter des symboles d'entraînement de même amplitude à des symboles de données envoyés par l'intermédiaire de sous-porteuses, et à calculer le signal de sortie envoyé par l'intermédiaire des sous-porteuses, et ; b) à envoyer le signal de sortie calculé par l'intermédiaire des sous-porteuses.
