1. A method for transmitting a signal in a communication system, the method comprising:
receiving an information vector to transmit;
generating a first structured low density parity check (LDPC) codeword vector including a first part mapped to the information vector and a second part mapped to a parity vector by encoding the information vector using a structured LDPC coding scheme supporting a first coding rate;
transmitting the first structured LDPC codeword vector to a signal reception apparatus;
detecting an error occurred upon reception of the first structured LDPC codeword vector;
generating a second structured LDPC codeword vector including the first part, the second part, and a third part mapped to an additional parity vector by encoding the information vector using a structured LDPC coding scheme supporting a second coding rate; and
transmitting the third part of the second structured LDPC codeword vector to the signal reception apparatus.
