Claim 0:
1. Channel encoder for encoding a frame, comprising:
a multi-mode redundancy encoder for redundancy encoding the frame in accordance with a certain coding mode from a set of different coding modes, wherein the multi-mode redundancy encoder is configured to be capable of encoding the frame using each coding mode in the set,
wherein the coding modes are different from each other with respect to an amount of redundancy added to the frame, wherein the multi-mode redundancy encoder is configured to output a coded frame comprising at least one code word; and
a colorator for applying a coloration sequence to the at least one code word;
wherein the coloration sequence is such that at least one bit of the code word is changed by the application of the at least one of coloration sequence, wherein the colorator is configured to select the specific coloration sequence in accordance with the certain coding mode,
wherein the channel encoder further comprises:
a data splitter for splitting the frame into a plurality of data words, wherein the multi-mode redundancy encoder is configured to encode each of the plurality of data words according to the certain coding mode to acquire a plurality of code words,
wherein the colorator is configured to apply the specific coloration sequence to each code word in a predefined number of the code words or in a predefined subset of the plurality of code words.
