Abstract
A decoding method for low density parity code is provided. The method includes performing an iterative decoding operation for a codeword, wherein a plurality of Log-Likelihood-Ratios correspond respectively to a plurality of data bits of the codeword; determining whether the iterative decoding operation is successful; determining whether a perturbation condition is met if the iterative decoding operation is not successful; performing protect operation for a first Log-Likelihood-Ratio among the Log-Likelihood-Ratios, and performing a perturbation operation for a plurality of second Log-Likelihood-Ratios among the Log-Likelihood-Ratios, wherein the second Log-Likelihood-Ratios are different to the first Log-Likelihood-Ratio; and re-performing the iterative decoding operation for the codeword after finishing the perturbation operation.
