    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: A signal reception method and apparatus for a communication system. One input unit and dc−1 delay nodes each receive one input message. A comparison unit compares magnitudes of the input messages being input to the dc−1 delay nodes, and outputs an input message having a minimum magnitude as an output message. After the comparison unit outputs the output message, a controller cyclic-shifts the input messages being input to the one input unit and the dc−1 delay nodes according to a control signal.

    摘要: Provided is an apparatus and method for receiving signals in a communication system. A first processor inputs dc input messages through dc input nodes, respectively, generates one output message from the dc input messages using a predetermined operation scheme, and outputs the output message to dc output nodes. A corrector inputs output messages output from the dc output nodes through dv input nodes, corrects the input dv output messages using a predetermined correction value, and outputs the dv output messages corrected using the correction value to dv input nodes of a second processor.
