ABSTRACT:
A method and a device for generating codes in the transmission of data via a communications system having at least two subscribers, in which a first subscriber receives at least one data word and forwards the data word or an at least partially changed data word to at least one second subscriber, the data being represented as bits which are able to assume two different values, and at least two bits of a data word are coded in at least three bits in such a way that in the three coded bits always at least two bits of the same value follow each other and that, after the reception of one or two of the three coded bits, one may already be able to decide which first code bit is to be emitted.
