Apparatus and method for coding/decoding block low density parity check code in a mobile communication system |
摘要 |
<p>A method for generating a parity check matrix of a block LDPC code is disclosed. The method includes determining a size of the parity check matrix based on a coding rate and a codeword length; dividing a parity check matrix with the determined size into a predetermined number of blocks; classifying the blocks into blocks corresponding to the information part; arranging permutation matrixes in predetermined blocks from among the blocks classified as the first parity part, and arranging identity matrixes in a full lower triangular form in predetermined blocks from among the blocks classified as the second parity part; and arranging the permutation matrixes in the blocks classified as the information part such that a minimum cycle length is maximized and weight values are irregular on a factor graph of the block LDPC code.</p> |
