Abstract: front page image
(EN)The present invention relates to a superheterodyne RF repeater and a relay method, which can maximally utilize a normal cyclic prefix (CP) with a time of 4.7µs in a long term evolution (LTE) orthogonal frequency division multiple access (OFDMA) mobile communication system. A relay device for the mobile communication system, according to one aspect of the present invention, is a relay device for superheterodyne amplification, comprising: a frequency-down converter for converting a received signal of a high frequency band into a signal of a intermediate frequency band; an IF filter for performing filtering so as to obtain a signal of a desired intermediate frequency band from the signal of the converted intermediate frequency band; and a frequency-up converter for converting the signal of the intermediate frequency band outputted from the IF filter into the signal of the high frequency band, wherein the frequency-down converter converts the signal of the high frequency band into the signal of the intermediate frequency band over 500MHz and outputs the converted signal, and the IF filter can be a filter having a time delay below 1µs.
(FR)La présente invention concerne un répéteur RF superhétérodyne et un procédé de relais, capables d'utiliser au maximum un préfixe cyclique (CP) normal avec un temps de 4,7µs dans un système de communications mobiles à accès multiple par répartition orthogonale en fréquence (OFDMA) de type Long Term Evolution (LTE). Un dispositif de relais pour le système de communications mobiles, selon un aspect de la présente invention, est un dispositif de relais pour amplification superhétérodyne, comportant: un convertisseur abaisseur de fréquence destiné à convertir un signal reçu d'une bande de hautes fréquences en un signal d'une bande de fréquences intermédiaires; un filtre IF destiné à effectuer un filtrage de façon à obtenir un signal d'une bande souhaitée de fréquences intermédiaires à partir du signal de la bande de fréquences intermédiaires convertie; et un convertisseur élévateur de fréquence destiné à convertir le signal de la bande de fréquences intermédiaires issu de la sortie du IF pour donner le signal de la bande de hautes fréquences, le convertisseur abaisseur de fréquence convertissant le signal de la bande de hautes fréquences en signal de la bande de fréquences intermédiaires au-dessus de 500MHz et émettant le signal converti, et le filtre IF pouvant être un filtre présentant un retard temporel inférieur à 1µs.
