Claim 0:
1. A method for performing low-density parity-check (LDPC) decoding, the method comprising:
receiving soft bits associated to an LDPC codeword; and
performing LDPC decoding of the soft bits using a parity check matrix, wherein:
each row of the parity check matrix corresponds to a lifted parity check of a lifted LDPC code;
at least two columns of the parity check matrix correspond to punctured variable nodes of the lifted LDPC code; and
the parity check matrix has row orthogonality between each pair of consecutive rows that are below a lowest row to which the at least two punctured variable nodes are both connected, wherein for each row below the lowest row to which the at least two punctured variable nodes are both connected, no column has a non-empty entry in two consecutive rows.
