Abstract
A channel interleaving method and apparatus in a communication system using a low density parity check (LDPC) code. Upon receipt of information data bits, an encoder encodes the information data bits into an LDPC codeword using a predetermined coding scheme. A channel interleaver interleaves the LDPC codeword according to a predetermined channel interleaving rule. A modulator modulates the channel-interleaved LDPC codeword into a modulation symbol using a predetermined modulation scheme.
