Abstract
A method and apparatus for decoding a signal in a communication system. The method and apparatus includes receiving a punctured codeword including information bit nodes and unpunctured parity bit nodes; analyzing the unpunctured parity bit nodes, and detecting at least one first block including the unpunctured parity bit nodes among a plurality of blocks each including parity bit nodes having the same importance among all parity bit nodes; and recovering said all parity bit nodes by serial-decoding parity bit nodes included in the first block according to decoding priorities of parity bit nodes, determined by reflecting the first block in a predetermined decoding priority determining algorithm.

A method for decoding a signal in a communication system, the method comprising:
- receiving a punctured codeword including information bit nodes and unpunctured parity bit nodes;
- analyzing the unpunctured parity bit nodes, and detecting at least one first block including the unpunctured parity bit nodes among a plurality of blocks each including parity bit nodes having a same importance among all parity bit nodes;
- and
- recovering said all said parity bit nodes by serial-decoding parity bit nodes included in the first block according to decoding priorities of parity bit nodes, determined by reflecting the first block in a predetermined decoding priority determining algorithm;
- wherein the decoding priorities are determined so as to preferentially decode parity bit nodes included in the first block, and sequentially decode parity bit nodes in order of parity bit nodes included in a block having a lower importance to parity bit nodes included in a block having a higher importance.
