摘要： An apparatus and a method for mapping a symbol are provided to symbol-map reliability of information bits and reliability of redundancy bits differently, thereby improving performance. A systematic encoder encodes transmission data(S410). An encoder outputs a plurality of information bits including added redundancy bits.

An information interleaver interleaves the punched information bit. The redundancy interleaver interleaves a punched redundancy bit(S430). A symbol mapping device maps the interleaved information bit and the interleaved redundancy bit on symbols respectively(S440).
