Abstract (en)

[origin: WO0228039A1] The invention relates to a method for preparing a data stream and for transmitting it via transmitters. In order to permit use of a transmitter, the data stream is first subjected to non-zero frequency encoding, for example by Manchester encoding. For a synchronous transmission (FIG) two data streams have to be transmitted, but not in a bi-directional manner. The data signal is initially not average-free. To make transmission with a transmitter all the same possible, the signal is first for example EXOR-linked with the clock signal. The two signals are then both transmitted (the clock signal is EXOR-linked with 0 to avoid different run times) and the original data stream is recovered by again EXOR-linking the two signals.
