Abstract

Disclosed is a method and apparatus for coding in a communication system. The coding method includes generating an information codeword vector from an information vector, generating a first vector in the information vector from an information part of a parity check matrix, generating a first parity codeword vector by performing an exclusive OR operation of the first vector and a second vector corresponding to a cyclically shifted version of the first vector, and generating a second parity codeword vector by performing an exclusive OR operation of the first vector, the first parity codeword vector, and a third vector. The third vector is a cyclically shifted version of a vector resulting from the exclusive OR operation of the first vector, the first parity codeword vector, and a fed-back third vector.
