Abstract
An encoding apparatus is provided. The encoding apparatus includes: a low density parity check (LDPC) encoder configured to generate an LDPC codeword formed of 16200 bits by performing LDPC encoding based on a parity check matrix, wherein the parity check matrix includes an information word sub-matrix and a parity sub-matrix, the information word sub-matrix being formed of a plurality of column groups each including 360 columns and being defined as a table indicating a position of one (1) present in each 360-th column.
