Abstract
In processing quasi-cyclic low-density parity-check (QC-LDPC) data, an input signal is received which includes decision and reliability information corresponding to unpadded data. Decision and reliability information corresponding to padded data is introduced into the input signal. Message passing is performed one or more times to obtain decoded data. This includes using (1) the decision and reliability information corresponding to the unpadded data and (2) the decision and reliability information corresponding to the padded data, where a preference is given to the decision and reliability information corresponding to the unpadded data over the decision and reliability information corresponding to the unpadded data during message passing. Zero padding is removed from the decoded data.
