APPARATUS AND METHOD FOR ENCODING USING TURBO CODE, AND UNIT AND METHOD OF PERMUTATION

摘要

PURPOSE: An encoding device and method using a turbo signal, a permutation switching device and permutation switching technique are provided to largely improve an error correction performance of a transceiving data by applying a permutation switching technique and a puncturing technique. CONSTITUTION: A first encoder(101) outputs a first parity bit by encoding a three bit received from a first to a third block which is comprised of each N numbers of bit. A permutation substituent(200) permutation substitutes the three bit. A second encoder(102) outputs a second redundant bit by encoding the substituted three bit. A puncturing device(300) controls the signal rate by selectively removes a first redundant bit and a second redundant bit by considering an encoding rate of a preset turbo signal.
