TURBO CODE FOR CONCATENATING HAMMING CODES AND METHOD AND APPARATUS FOR ENCODING AND DECODING THE SAME

摘要

PURPOSE: A turbo code for concatenating hamming codes and a method and an apparatus for encoding and decoding the same are provided to perform a turbo coding process by substituting hamming coded data for data having a value of 1 from turbo codes for generating codes of low distance. CONSTITUTION: A separator(100) outputs languages of a size K according to a timing control signal(C1) of a timing controller(110) to a hamming coder(102) and a selector(104). The hamming coder(102) performs a hamming coding process for data of k bits output from the separator(100) according to a timing control signal(C2) and outputs data of n bits. The selector(104) is operated by a timing control signal(C4). The selector(104) outputs selectively coded data of the hamming coder(102) to predetermined locations output from a lookup table(106). The selector(104) outputs data of K-k number output from the separator(100) to the remaining locations. A turbo coder(108) receives bits from the selector(104) according to a timing control signal(C5) and codes the bits.
