Abstract

Die Erfindung betrifft eine Detektionseinheit zur Detektion von in einem differentiell demodulierten Signal enthaltenen Datensymbolen, denen sendeseitig jeweils eine PN-Sequenz aus einem Sequenzvorrat zuweisbar ist. Die erfindungsgemäße Detektionseinheit weist folgende Einheiten auf: a) eine Sequenzbereitstellungseinheit, die zum Bereitstellen einer dritten Gruppe von abgeleiteten Sequenzen ausgebildet ist, wobei die dritte Gruppe zu jeder ersten PN-Sequenz eine abgeleitete Sequenz aufweist, die dieser ersten PN-Sequenz zugeordnet und aus dieser mittels logischer Verknüpfungen ableitbar ist, die jedoch nicht mit dieser identisch ist, und wobei sich die abgeleiteten Sequenzen der dritten Gruppe nur durch eine zyklische Verschiebung ihrer Chipwerte voneinander unterscheiden, b) eine mit der Sequenzbereitstellungseinheit verbundene Korrelationseinheit, die zum Berechnen von Korrelationsergebnissen durch Korrelieren des differentiell demodulierten Signals mit jeder der abgeleiteten Sequenzen der dritten Gruppe ausgebildet ist, und c) eine mit der Korrelationseinheit verbundene Auswerteeinheit, die zum Ableiten der werte der Datensymbole durch Auswerten der Korrelationsergebnisse ausgebildet ist. Die Erfindung betrifft weiterhin eine Sende-/Empfangsvorrichtung und eine integrierte Schaltung mit einer solchen Detektionseinheit.
