Abstract

En flerhet av kommunikasjonssignaler mottas. Hvert kommunikasjonssignal har en tilhørende kode. Minst to av kommunikasjonssignalene har en forskjellig spredefaktor. De tilhørende koder har en krypteringskodeperiode. En total systemresponsmatrise har blokker. Hver blokk har én dimensjon med en lengde M og en annen dimensjon med en lengde som delvis er basert på M og spredefaktoren for hver kommunikasjon. M er basert på krypteringskodeperioden. Data i den mottatte flerhet av kommunikasjonssignaler mottas ved bruk av den konstruerte systemresponsmatrise.
