Abstract
A method for performing low-density parity-check (LDPC) decoding by a communication apparatus may comprise the steps of: acquiring information on a shortening pattern; setting a log-likelihood ratio (LLR) value of a shortening part on the basis of the information on the shortening pattern so as to perform first decoding; and verifying validation of a corresponding codeword on the basis of a result of the first decoding.

A low-density parity-check (LDPC) encoding method for a communication device, the LDPC encoding method comprising:
- generating information;
- attaching a shortening pattern to the information;
- and
- performing LDPC encoding of a sequence of the information to which the shortening pattern is attached.
A low-density parity-check (LDPC) decoding method for a communication device, the LDPC decoding method comprising:
- obtaining information about a shortening pattern;
- performing first decoding by configuring a log-likelihood ratio (LLR) value of a shortening part based on the information about the shortening pattern;
- and
- verifying validity of a corresponding codeword based on results of the first decoding.
A communication device for performing low-density parity-check (LDPC) encoding, the communication device comprising:
