Multi-mode channel coding with mode specific coloration sequences

Abstract A 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 5 different coding modes, 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 including 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 10 application of the at least one of coloration sequence, wherein the specific coloration sequence is selected in accordance with the certain coding mode.
