Abstract
Systems and methods are provided for decoding a codeword encoded by a linear block code. A method may comprise performing a first decoding on a codeword using a first decoder, determining a number of satisfied check nodes and a number of unsatisfied check nodes for a symbol value of the codeword for a decoding result of the first decoding, generating a soft log-likelihood ratio (LLR) for the symbol value based on the number of satisfied check nodes and the number of unsatisfied check nodes, and performing a second decoding using a second decoder with the soft LLR as an input to the second decoder.
