| 1. A method for coding a semi-systematic block low-density parity check (LDPC) code, the method comprising the steps of:
receiving an information word;
coding the information word into a codeword including the information word, a first parity, a second parity, and a third parity,
based on one of a first parity check matrix and a second parity check matrix, depending on a size to be applied when generating
the information word into the semi-systematic block LDPC code;
puncturing a part having a degree being at least equal to a predetermined degree from the information word; and
generating the semi-systematic block LDPC code including the information word, a part of which being punctured, the first
parity, the second parity, and the third parity.
