Abstract

Devices, systems and methods for improving decoding operations of a decoder are described. An example method includes receiving a noisy codeword that is based on a transmitted codeword generated from a low-density parity-check (LDPC) code, the LDPC code having an associated parity matrix comprising N columns, wherein each of at least B columns of the parity matrix has a column weight that exceeds a predetermined column weight, processing the N columns based on a message passing algorithm, and determining, based on the processing, a candidate version of the transmitted codeword, wherein the processing for each of the N columns comprises performing a read operation, a variable node update (VNU) operation, and a check node update (CNU) operation on the first set and the second set, the read operation and the CNU operation on each of the at least B columns spanning two or more time-steps.
