ABSTRACT:
In a communication system, information data bits are encoded in a preset coding scheme when the information data bits are input, and a Low Density Parity Check (LDPC) codeword is generated. The LDPC codeword is interleaved according to a preset channel-interleaving rule. A channel-interleaved LDPC codeword is modulated in a preset modulation scheme and a modulation symbol is generated.
