Abstract

Es ist eine Sende- und Empfangseinheit angegeben mit einem Empfangszweig (1) und einem Sendezweig (2), welche jeweils zur Führung komplexer Signale (I, Q) ausgebildet sind, mit einer Steuereinrichtung (26), die einen Schalter (8) ansteuert, mit dem entweder eine Phasenregelschleife (30) auf sende- und empfangsseitig vorgesehene Frequenzumsetzer (11 bis 14) durchgeschaltet ist zum Bereitstellen einer gemeinsamen Trägerfrequenz oder je eine unabhängig arbeitende PLL (30, 40) für Sende- und Empfangszweig (1, 2) vorgesehen ist. Hierdurch ist es möglich, daß beispielsweise der Sender mit Direktumsetzung arbeitet, während der Empfänger beispielsweise mit Low-IF-Prinzip arbeiten kann. Die Erfindung ist für OFDM-Mehrträgersysteme geeignet.
