Abstract

Et trådløst kommunikasjonssystem, for eksempel et OFDM-system, som anvender flere bærefrekvenser hver med et tilknyttet frekvensbånd. En sektorsender i basestasjonen i systemet sender ordinær signalering, for eksempel brukerdata, i sitt eget tildelte bånd. I tillegg sender basestasjonssenderen i sektoren periodisk toppsignaler i sitt eget frekvensbånd og frekvensbåndene benyttet av tilliggende sektorsendere ved deres ordinære signalering. Toppsignalene, som er høyeffektssignaler med kort varighet og med sektortransmisjonseffekten konsentrert på én eller noen få toner, kan enkelt detekteres. Hvert toppsignal kan enkelt identifiseres ved kildesektorsenderen i basestasjonen, for eksempel basert på tone. Et mobilt knutepunkt, som er innstilt på ett enkelt bærefrekvensbånd, mottar flere toppsignaler, identifiserer kildene til de mottatte toppsignaler, sammenlikner styrken til de mottatte toppsignaler, og tar omrutingsavgjørelser, uten å måtte skifte bærefrekvensbånd.
