Title (EN) A METHOD FOR SELECTING A SIGNAL, AND A CELLULAR RADIO SYSTEM
(FR) PROCEDE DE SELECTION D'UN SIGNAL ET SYSTEME RADIO CELLULAIRE
Abstract: front page image
(EN)The invention relates to a transmission method and a cellular radio system comprising base stations and at least one vocoder. The base stations and the vocoder transmit a signal to each other. The base stations transmit a signal to the vocoder substantially simultaneously, the vocoder receiving the simultaneously transmitted signals at different moments of reception. The cellular radio system comprises comparing means for comparing the moments of reception of the signals to a predetermined time window, measuring means for measuring and comparing the quality of the received signals, and selection means for selecting a signal on the basis of the aforementioned signal measurement and comparison.
(FR)Cette invention concerne un procédé d'émission ainsi qu'un système radio cellulaire qui comprend des stations de base et un ou plusieurs vocodeurs, les stations de base et les vocodeurs émettant un signal les uns vers les autres. Les stations de base envoient quasi simultanément un signal au vocodeur, et le vocodeur va recevoir les signaux émis quasi simultanément à des moments de réception différents. Le système radio cellulaire comprend également un système de comparaison qui va comparer les moments de réception des signaux à un créneau temporel prédéterminé, un système de mesure qui va mesurer et comparer la qualité des signaux reçus, ainsi qu'un système de sélection qui va choisir un signal en fonction des mesures et des comparaisons de signaux susmentionnées.
