Abstract
Data blir sendt i et kodedelt multippel aksess kommunikasjonssystem (figur 1). En kanalrespons blir gitt som en kanalresponsmatrise H som tilnærmer en kanal som dataene vil oppleve etter sending. Dataene blir spredt (14) og de spredte dataene blir prosessert (15) med kanalresponsmatrisen H. De spredte og prosesserte dataene blir sendt. Dataene blir mottatt og gjenvunnet fra de sendte spredte og prosesserte dataene.
