An adaptive-normalized/offset min-sum (AN-/AO-MS) algorithm for decoding low-density parity-check (LDPC) codes is proposed. Unlike the normalized/offset min-sum (NMS/OMS) algorithm, the normalization/offset factor is adaptively adjusted according to the state of check nodes in each iteration. Simulation results show that the proposed AN-/AO-MS algorithm can perform better than the NMS/OMS algorithm while still preserving the low complexity of the min-sum algorithm.
