Abstract

Foreliggende oppfirmelses fremgangsmåte tilveiebringer effektiv ressursallokering med hensyn til underbærer, bit og korresponderende effekt for QoS for sarmtidstjenester i flerbruker-OFDM- systemer. Oppfirmelsen drar fordel av instantan kanalvirming i underbæreren og bitallokering som ved bruk av en iterativ tilnærming.
