1. A method to decode low-density parity check (LDPC) encoded data using a parity check matrix having a plurality of layers, comprising:

  • receiving a plurality of values at a decoder, each value of the plurality of values representing one of a plurality of bits of an LDPC codeword encoded using the parity check matrix;

    decoding the LDPC codeword using layered scheduling; and

    applying a functional adjustment to an approximation of belief propagation used during the decoding, wherein the applying includes applying a first functional adjustment parameter to a first layer and applying a second functional adjustment parameter to a second layer to provide an estimate of a codeword, wherein the first functional adjustment parameter is different from the second functional adjustment parameter.
