Abstract
An apparatus and method for coding a block Low Density Parity Check (LDPC) code having a variable coding rate. The apparatus receives an information word and encodes the information word into a block LDPC code based on one of a first parity check matrix and a second parity check matrix, depending on a coding rate to be applied when generating the information word into the block LDPC code.
