Abstract

Teknikk for å redusere den sendereffekt som trengs for sending av meldinger fra en aksessterminal (106) er beskrevet. Særlig siktes på reduksjon av interferens overfor sendinger fra andre aksessterminaler. I et bestemt aspekt fastlegges de meldinger som skal sendes og/eller kodes slik at de kan detekteres ved forskjellig signalkvalitet på mottakerstedet som kan være i et aksesspunkt (104) Kodeordene kan bestemmes ut fra forskjellig avstand til sine nærmeste nabokodeord. I et annet aspekt tilordnes meldinger som skal sendes forskjellige punkter i en signalkonstellasjon, hvor punktene er plassert slik at de kan mottas ved forskjellig signalkvalitet. Kodeordene som kan mottas ved dårligere kvalitet kan tilordnes meldinger som mer sannsynlig blir sendt ved større sendereffekt (så som når aksessterminalen. (106) er lengre unna) eller meldinger som sendes ofte.
