A method of processing a bitstream comprising a plurality of encoded codewords, the method comprising: obtaining an encoded codeword comprising a plurality of bits, each of the plurality of bits being associated with a bit position in the codeword; obtaining a puncturing code designating bit-positions of the codeword to be punctured prior to decoding; obtaining a modified codeword by modifying at least one bit of codeword at a bit-position designated by the puncturing code in order to keep the value of a Running Digital Sum (RDS) and/or a Running Alternate Sum (RAS) bounded. Embodiments make it possible to attain improved performances in terms of BER (bit error ratio). |
