Abstract

In ciascuna cella di un sistema radiomobile con accesso a divisione di codice, si effettua un controllo di potenza sulla tratta stazione base-mezzo mobile a partire dal rapporto segnale/interferenza di ciascun mobile. Il controllo è realizzato da un dispositivo (CP), associato alla stazione base (SB), il quale, per tutto un periodo in cui i rapporti segnale/interferenza si mantengono validi, assegna a ciascun canale di traffico verso i mobili attivi (M1 ... MN) una frazione Pi = ?iP/N (con N = numero dei mobili attivi) della potenza complessiva P disponibile per la trasmissione delle informazioni di traffico verso i mobili, determinata in modo da equalizzare il rapporto segnale/interferenza di tutti i mobili e mantenere costante la potenza complessiva per un dato numero di canali attivi.(Fig. 1).
