Abstract

Fremgangsmåte og system for interferenskansellering (IC). Et aspekt gjelder en trafikkinterferenskansellering, og et annet gjelder en felles slik interferenskansellering for pilot-, overhead og trafikkdata. Nok et aspekt gjelder forbedret kanalestimering, og enda et gjelder tilpasning av forsterkningen for sendte underkanalsignaler.
