802.11AY 11AY LDPC CHANNEL CODING FRAMEWORK FOR 802.11AY AND LARGER BLOCK-LENGTH LDPC CODES FOR 11AY WITH TWO-STEP LIFTING MATRICES AND IN-PLACE PROPERTY
802.11AY 11AY LDPC CHANNEL CODING FRAMEWORK FOR 802.11AY AND LARGER BLOCK-LENGTH LDPC CODES FOR 11AY WITH TWO-STEP LIFTING MATRICES AND IN-PLACE PROPERTY
The present invention relates to a method and a device for coding a code word. The present invention provides a channel coding framework for 802.11ay and a large block length LDPC codes for 11ay using an in-place property and a two-step lifting matrix. A device for decoding a code word includes: a memory receiving an encoded code word based on a two-step matrix and a low density parity check (LDPC) code H-matrix; and a memory decoding the received code word. A device for encoding a code word includes: a memory for storing information bits to be encoded; and a processing circuit encoding the code word based on the LDPC code H matrix and the two-step matrix. A code length of the LDPC code H matrix lifted by a two-step lifting matrix is multiples of 672 bits. The LDPC code H matrix may be a IEEE 802.11ad standard LDPC coding matrix. The two-step lifting matrix may be one among the multiple two-step lifting matrices to generate a family of LDPC codes.
