Decoder and decoding method for a communication system

A decoder for a communication system, the decoder comprising:

• a channel detection module configured to i) receive initial estimates of respective code words, wherein the initial estimates of the respective code words correspond to a signal received via a communication channel, ii) arrange the initial estimates of the respective code words into a plurality of groups, and iii) generate probability information associated with data bits of the respective code words in the plurality of groups, wherein the probability information indicates probabilities of decoding decisions of the data bits;
• a computation module configured to generate bit estimations for each of the data bits based on i) the probability information, and ii) feedback information;
• and
• a decoding module configured to i) selectively generate, based on the bit estimations for each of the data bits, the feedback information, and ii) selectively generate, based on the bit estimations for each of the data bits, an estimate signal corresponding to the respective code words.
