Abstract (en)
[origin: DE19743167A1] The invention relates to a communications system for digital data transmission in the long, medium and short-wave ranges. The data to be transmitted are advantageously distributed over several channels (ZF0, ZF1, ZF2) and then transmitted in each channel in carrier modulation mode (Mod). This means that the level of complexity of the equalisation filter used at the receiver end remains low, even with long anticipated echo transmission times. One of the channels is preferably used as a reference channel. Synchronisation parameters are drawn from this reference channel and applied to all of the channels.
