    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： A method for determining reserved tone set to be used for reducing a Peak to Average Power Ratio (PAPR) is provided in a transmission apparatus of an Orthogonal Frequency Division Multiplexing (OFDM) communication system. The shift value is determined based on a subcarrier spacing interval(x) and a number of spaced symbols(y) of a scattered pilot pattern and OFDM symbol indices(1). The reserved tone set( S l ) for OFDM symbols is determined by shifting each of subcarriers( i k ) of a predetermined reserved tone set( S 0 ) by the determined shift value.

    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.
