| 1. A method for generating a parity check matrix of a Low Density Parity Check (LDPC) code including an information word part,
a first parity part and a second parity part, the method comprising the steps of:
determining parameters required for coding according to a coding rate and a code length;
generating a seed matrix according to values of the parameters;
generating a plurality of cell matrices according to the values of the parameters;
placing the generated cell matrices in place of ‘1’s from among elements of the seed matrix; and
placing zero matrices in place of ‘0’s from among the elements of the seed matrix, each of the zero matrices having a size
equal to a size of the cell matrix.
