Abstract

I visse typer transmisjoner som anvender nQAM kan det være ønskelig å anvende en kontrollkanal lagt ovenpå en nQAM datakanal. I slike tilfeller er det svært ønskelig å være i stand til å separere kontrollkanaldata fra bruker- data uten anvendelse av høyere ordens protokollsjikt. For applikasjoner i multibærersystemer med variable bit-lasting er det spesielt ønskelig at kontrollkanaldataene kan separeres fra brukerdatene idet verdiene av n, dvs. bil- lastingen, eller konstellasjonsidentifisereren er ukjent. Binære bits overføres ved å anvende nQAM modulering. De binære data omfatter både brukerdata og kontrolldata. Dette betyr at en kontrollkanal legges oppå en brukerdatakanal innen den samme nQAM-konstellasjon. Separering av nevnte kantrolldata forbedres ved å arrangere kontrolldatapunkter som har enten unike fase-, eller unike amplitydeverdier. Disse unike verdier benyttes ikke for brukerdatapunkter.
