Summary:Methods and apparatuses for coding a codeword. An apparatus for decoding the codeword includes a memory configured to receive the codeword encoded based on a low-density parity check (LDPC) code H-matrix and a two-step lifting matrix and processing circuitry configured to decode the received codeword. An apparatus for encoding the codeword includes memory configured to store information bits to be encoded into the codeword and processing circuitry configured to encode the codeword based on based on a LDPC code H-matrix and a two-step lifting matrix. A code length of the LDPC code H-matrix lifted by the two-step lifting matrix is an integer multiple of 672 bits. The LDPC code block H-matrix may be an IEEE 802.11ad standard LDPC coding matrix. The two-step lifting matrix can be one of a plurality of two-step lifting matrices to generate a family of LDPC codes.
