摘要：
An apparatus for transmitting data in a communication system using a Low Density Parity Check (LDPC) matrix is provided. The apparatus includes an interleaver for interleaving a descending bit-ordered codeword having a predetermined size and in accordance with a predetermined modulation scheme; and a bit mapper for mapping codeword bits constituting the interleaved codeword in accordance with a predetermined mapping scheme that takes into account degrees of the codeword bits and reliability characteristics of modulation symbol-constituting bits based on the predetermined modulation scheme.
