    • Disclosed are an apparatus and a encoding method using a turbo code and a unit and a method of permutation. The apparatus for encoding using a turbo code according to an exemplary embodiment of the present invention includes: a first encoder that encodes 3 bits inputted from first to third blocks each of which is formed of N bits respectively, with recursive systematic convolutional codes to output a first parity bit; a permutation unit that permutates the 3 bits; a second encoder that encodes the permutated 3 bits with the recursive systematic convolutional codes to output a second parity bit; and a puncturing unit that optionally removes the first parity bit and the second parity bit in consideration of a coding rate of a predetermined turbo code to control the coding rate.

    • A pragmatic trellis code modulation decoder including a demodulator for receiving a modulated signal and computing coordination values of symbols of the modulated signal on an I-axis and Q-axis in a constellation; a coset mapper for generating 3-bit soft decision data based on the computed coordinate values; a viterbi decoder for receiving 3-bit soft decision data and generating 1-bit data as a coded data by decoding the 3-bit soft decision data; a re-encoder for receiving the 1-bit data from the viterbi decoder and obtaining un-coded information in order to compute an un-coded data; a sector phase quantizer for obtaining I channel and Q channel information based on the coordination values from the demodulator in order to obtain un-coded data; a time delayer for delaying output of the sector phase quantizer until the re-encoder outputs the un-coded information; and a non-coded code decoder for computing the un-coded data.
