Title (EN) SIMULCAST HANDOFF METHOD COMPENSATING FOR CABLE LENGTH DIFFERENCES
(FR) PROCEDE DE TRANSMISSION 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, in which cellular radio system the base stations and the vocoder transmit to each other a signal, the base stations transmitting signals to be vocoder substantially simultaneously, and wherein the vocoder receives the substantially simultaneously transmitted signals at different moments of reception, the cellular radio system comprising measuring means for measuring the delay difference between the different moments of reception of the signals received by the vocoder, and delaying means for delaying, if required, the signals to be transmitted to the base stations in such a way that the base stations receive the signals transmitted by the vocoder substantially simultaneously.
(FR)L'invention concerne un procédé de transmission et un système radio cellulaire comprenant des stations de base et au moins un vocodeur et dans lequel les stations de base et le vocodeur se transmettent réciproquement un signal, les stations de base émettant des signaux en direction du vocodeur de façon pratiquement simultanée et le vocodeur recevant ces signaux à différents moments de réception. Ce système radio cellulaire comprend des moyens de mesure servant à mesurer la différence de retard entre les différents moments de réception des signaux par le vocodeur, ainsi que des moyens de retard servant à retarder, si nécessaire, les signaux à transmettre aux stations de base, de telle sorte que ces dernières reçoivent les signaux transmis par le vocodeur de façon pratiquement simultanée.
