Abstract
Techniques for decoding a low-density parity check (LDPC) can include determining an asymmetric ratio of bit errors read as logic zero to bit errors read as logic one. The energy of each variable node of the LDPC codeword can be computed. For each variable node having an energy greater than a threshold energy, the variable node can be added to a collection of candidate bits for bit flipping. The asymmetric ratio can then be applied to flip bits in the collection of candidate bits to decode the LDPC codeword.
