Abstract

Das Verfahren und die Vorrichtung dienen zur Vermeidung von Störungen in nach dem Prinzip der Chirp-Modulationstechnik arbeitenden Übertragungssystemen, bei denen ein Signal p in einer Sendestation (TX) expandiert und nach der Übertragung in einer Empfangsstation (RX1; RX2; RX3) wieder komprimiert wird. Dabei wird der expandierte Puls pe in der Empfangsstation (RX1; RX2; RX3) einem Filter (SAW3, SAW4) zugeführt, durch das für jedes von n Frequenzbändern (fb1, ..., fbn) Teilsignale (s1, ..., sn) gebildet werden, von denen wenigstens diejenigen, die einem Übertragungskanal zugehören, in bezug auf vorliegende Betriebszustände geprüft und anschliessend ganz oder teilweise addiert und zu einem komprimierten Summensignal pk zusammengefügt werden.
