Claim 10:
11. A method for performing low-density parity-check (LDPC) encoding, the method comprising:
obtaining information bits of a codeword; and
performing encoding of the information bits to compute parity bits of an LDPC codeword according to a lifted parity check matrix, wherein:
each row of the lifted parity check matrix corresponds to a lifted parity check of a lifted LDPC code,
at least two columns of the lifted parity check matrix correspond to punctured variable nodes of the lifted LDPC code, and
the lifted 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.
