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.

摘要： An apparatus is provided for transmitting a signal in a communication system using a Low Density Parity Check (LDPC) code. A controller determines a number of ‘0’s to be inserted in information data according to a first coding rate to be applied when generating the information data into an LDPC code, and determines the number of ‘0’s to be removed from the LDPC code. A ‘0’ inserter inserts ‘0s’ in the information data according to control of the controller. An LDPC encoder generates the LDPC code by encoding the ‘0’-inserted signal according to a first parity check matrix. A ‘0’ remover removes the inserted ‘0’s from the LDPC code.
