摘要：
An apparatus and a method are provided for encoding and decoding in a broadcasting/communication system using a Low Density Parity Check (LDPC) code. A weight-1 position sequence conversion procedure is performed on an initial parity check matrix. Shortening is applied on an information word. A codeword is generated by LDPC encoding the information word using a parity check matrix generated by performing the weight-1 position sequence conversion procedure. Puncturing is then applied to the codeword.
