    摘要: The present invention provides an apparatus and method of transmitting/receiving a signal supporting a plurality of code rates in a communication system using a block LDPC code. The child parity check matrix used for encoding/decoding includes a plurality of parity blocks comprising permutation or zero matrixes in order to facilitate encoding. Furthermore, the used child parity check matrix has an extended structure of a parent parity check matrix. Puncturing can be employed in order to obtain more code rates. Hence a parent codeword, a child codeword having code rate less that the code rate of the parent codeword, and a child codeword having code rate greater than the code rate of the parent codeword can be generated by only using the child parity check matrix.
