A low-density parity check (LDPC) decoder is provided for decoding low-density parity check (LDPC) encoded data wherein an adaptive check node approximation is performed at the check node processor utilizing the smallest magnitude log-likelihood ratio (LLR) and the second smallest magnitude log-likelihood ratio (LLR) to adapt to the current conditions at the check node.
