Abstract

Transmission method in which angle-modulated pulses with temporally opposite angle modulation are generated in the receiver during the duration of the pulse, which pulses are superimposed by means of a first superimposing element (8, 9), in each case in pairs, into a folded pulse, whereby the folded pulses transmitted to the receiver, after a modulation process, carry information impressed upon them, and these folded pulses are filtered at the receiver through two parallel-connected, complementary dispersion filters with frequency-dependent group delay characteristics, whereby the frequency-dependent group delay characteristics of the two dispersion filters are matched to the angle-modulation, in each case, of one of the two pulses forming in their superposition the folded pulse, in such a way that at the output of the dispersion filter, in each case, a combined signal appears that consists of one compressed pulse with increased amplitude and one expanded pulse with decreased amplitude, whereby the signals at the outputs of both dispersion filters at the receiver are combined by means of a second superimposing element.
