摘要： An apparatus and method for encoding a channel in a communication system using a Low-Density Parity-Check (LDPC) code. The method includes determining a number of parity bits to be subjected to puncturing; dividing the parity bits at predetermined intervals, and determining a number of puncturing bits, which are subjected to puncturing within the predetermined intervals; determining positions of puncturing parity bits corresponding to the determined number of puncturing bits; and repeatedly performing puncturing on the puncturing parity bits corresponding to the determined positions at the predetermined intervals. The predetermined intervals are determined by dividing a length of parity bits by a length of one column group in a parity-check matrix.

摘要： An apparatus and method for mapping and demapping signals in a system using a Low Density Parity Check (LDPC) code are provided. In the method, LDPC codeword bits are written column-wise and read row-wise, substreams are generated by demultiplexing the read bits using a demultiplexing scheme, and bits included in each of the substreams are mapped to symbols on a signal constellation. The demultiplexing scheme is determined corresponding to a modulation scheme used in the signal transmitter, a length of the LDPC codeword, and a number of the substreams.
