Abstract
Verfahren zur drahtlosen Übertragung von Daten unter Verwendung von Zeitschlitzen, bei dem mindestens einer Verbindung mehrere, in der Zeit und Frequenz nicht disjunkte Kanäle gleichzeitig zugeordnet sind. Dabei wird jedem Datensymbol vor der Übertragung eine kanalspezifische Signalform aufmoduliert. Die unterschiedlichen Kanäle basieren dabei auf unterschiedlichen zueinander orthogonalen Signalformen.
