Abstract

IN UN SISTEMA DI COMUNICAZIONE TRA MEZZI MOBILI SI TRASMETTONO SU UNO STESSO CANALE FISICO (6) FLUSSI INFORMATIVI A VELOCITA' VARIABILE EMESSI DA SORGENTI DIVERSE (CV1, CS1; CV2, CS2) RELATIVI A UNA STESSA COMUNICAZIONE. OGNI STAZIONE MOBILE (M1 Mh) E LA PARTE FISSA (B1 Bn, RNC) DEL SISTEMA COMPRENDONO UN'UNITA' (UC1, UC2) DI CONTROLLO DELLA TRASMISSIONE A VELOCITA' VARIABILE CHE ALLOCA DINAMICAMENTE I BIT DISPONIBILI AI SINGOLI FLUSSI TENENDO CONTO DELLE ESIGENZE DELLE SORGENTI (CV1, CS1; CV2, CS2), DELLE CONDIZIONI DEL CANALE (6) E DELLO STATO DI OCCUPAZIONE DEL SISTEMA.(FIG. 1).
