Apparatus and method for transmitting and receiving signal in a communication system |
摘要 |
An apparatus and method for transmitting and receiving a signal in a communication system are provided. The signal transmission apparatus generates a parity check matrix for an LDPC code in accordance with a code rate to be used and generates a codeword vector by encoding an information vector using the parity check matrix. When the code rate is a first code rate, the signal transmission apparatus generates a first parity check matrix as the parity check matrix for the LDPC code. When the code rate is the second code rate, the signal transmission apparatus generates a second parity check matrix supporting a second code rate lower than the first code rate by adding columns of a degree of 1 and columns of a degree of 2 to the first parity check matrix and generates the second parity check matrix as the parity check matrix for the LDPC code.
