Abstract
Methods and apparatus are disclosed for decoding low-density parity check (LDPC) encoded data using a parity check matrix having a plurality of layers. The apparatus includes a decoder having circuitry to decode, layer by layer, a LDPC codeword utilizing functional adjustments and an algorithmic approximation to belief propagation to provide an estimate of the LDPC codeword, the functional adjustments including layer specific parameters for at least two layers of the parity check matrix associated with the LDPC codeword.
