Abstract
While decoding a representation, imported from a channel, of a codeword that encodes K information bits as N>K codeword bits, by updating estimates of the codeword bits in a plurality of iterations, the iterations are interrupted upon satisfaction of an interruption criterion that is either an order-dependent interruption criterion or an interruption criterion that includes an estimate of mutual information of the codeword and a vector that is used in the decoding iterations. Either the iterations are terminated or the iterations are resumed after one or more elements of one or more vectors used in the iterations is/are modified.
