Abstract
Systemer og fremgangsmåter er fremvist for materforbindelseskonfigurasjoner for lagdelt modulasjon. Ett materforbindelsessystem anvender materforbindelsespunktstråler til antenner i atskilte dekningsområder for å åpne for frekvensgjenbruk. Et annet system anvender smal strålebredde materforbindelsesantenner for å belyse individuelle satellitter hvilket også åpner for frekvensgjenbruk. Nok et system benytter lagdelt modulasjon i materforbindelsen. Et annet materforbindelsessystem anvender høyere ordens synkron modulasjon til satellittmaterforbindelsen som benyttes i de lagdelte modulasjonsnedlinksignalene.
