Abstract

Et mangfold av sendte datasignaler blir mottatt i en mottaker. Mottakeren måler en kanalrespons assosiert med de sendte datasignalene. En systemrespons blir bestemt. Systemresponsen blir utvidet til å være stykkevis ortogonal. De mottatte datasignalenes data blir gjenvunnet basert delvis på den utvide systemresponsen.
