HARQ apparatus and method using an LDPC code |
摘要 |
<p>An apparatus and method for transmitting a signal in a communication system. An information vector is encoded using a structured low density parity check (LDPC) coding scheme supporting a first coding rate, to generate a first structured LDPC codeword vector including a first part mapped to the information vector and a second part mapped to a parity vector. The first structured LDPC codeword vector is transmitted to a signal reception apparatus. If there is an error in the first structured LDPC codeword vector, the information vector is encoded using a structured LDPC coding scheme supporting a second coding rate, to generate a second structured LDPC codeword vector including the first part, the second part, and a third part mapped to an additional parity vector of the information vector. The third part is transmitted to the signal reception apparatus.
