Abstract
A variable code rate adaptive encoding/decoding method using LDDC code is disclosed, in which an input source data is encoded using the LDPC (low density parity check) code defined by a first parity check matrix configured with a plurality of submatrices. The present invention includes the steps of generating a second parity check matrix corresponding to a code rate by reducing a portion of a plurality of submatrices configuring a first parity check matrix according to the code rate to be applied to encoding an input source data and encoding the input source data using the second parity check matrix.
