ABSTRACT:
A method and apparatus are provided for decoding a sequence of code words into a sequence of data words. Each code word includes an encoded data word and an indicator bit. The encoded data word is extracted unchanged into a respective unencoded data word if an indicator bit has a first binary value and is extracted into the unencoded data word and then complemented if the indicator bit has a second, opposite binary value.
