    摘要: Methods and apparatus are provided for transmitting data in a broadcasting system. Input data is encoded by an encoder. A first demultiplexer generates first transmission symbols using the encoded data. The first transmission symbols are modulated, and the modulated first transmission symbols are transmitted. A second demultiplexer generates second transmission symbols using at least a portion of the encoded data. The second transmission symbols are modulated and the modulated second transmission symbols are transmitted.

    摘要: Methods and apparatuses are provided for achieving maximum diversity gain through channel coding based on a Low-Density Parity-Check (LDPC) code in a multiple antenna communication system. A method includes determining a parity-check matrix; generating a codeword using the parity-check matrix; puncturing a part of an information word; dividing a parity into a plurality of partial parities based on a number of transmit antennas; transmitting an unpunctured part of the information word and a partial parity over a first antenna; and transmitting at least one other partial parity over at least one other transmit antenna.

    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.
