    摘要: A code puncturing apparatus and method is provided. The apparatus includes: a codeword selection unit selecting continuous n−1-number of mother codewords from mother codewords generated from k-bit effective information, where k denotes a natural number, and one redundancy bit; and a puncturing unit selecting k-number of redundancy bits from redundancy bits included in the n−1-number of mother codewords, deleting remaining redundancy bits, and rearranging the n−1-number of mother codewords into an n·k bit-target codeword. Accordingly, a code rate of an Error Control Code (ECC) can be raised.
