Abstract (en)
In a transmitter network comprising a plurality of transmitters having the same transmitter frequency there are so-termed echo regions in which both transmitters may be received about equally strongly. In these regions the receivers are to comprise means for suppressing the received signal from one of the transmitters that has the features of an undesired echo signal. For reducing the complexity of the receivers, which complexity strongly depends on the echo time of the echo signal, the signal transmitted by one of the transmitters is delayed in such a way according to the invention that the average echo time in the echo region is minimized. <IMAGE>
