    摘要: A method and apparatus for Convolutional Turbo Coding (CTC), and an apparatus for a turbo encoder are provided. The method for CTC includes the steps of encoding information bits A and B using a constituent encoder, and outputting parity sequences Y1 and W1, interleaving the information bits A and B using a CTC interleaver to obtain information bits C and D, and encoding the interleaved information bits C and D using the constituent encoder to obtain parity sequences Y2 and W2, interleaving the information bits A and B, the parity sequences Y1 and W1 and the parity sequences Y2 and W2, respectively, wherein the bits in at least one of a bit group constituted of the information bits A and B, a bit group constituted of the sequences Y1 and W1, and a bit group constituted of the sequences Y2 and W2 are alternately mapped to bits of constellation points with high reliability and low reliability and puncturing the interleaving result to obtain the encoded bit sequences.

    摘要: A Base Station (BS) includes an apparatus is configured to reduce a MAP overhead in a broadband wireless communication system. The BS operation method for reducing an overhead in a broadband wireless communication system includes transmitting control information for initial transmission and changing first information among the control information transmitted at the initial transmission into second information needed at a retransmission time when there is a retransmission request for the initial transmission. The BS also transmits control information for retransmission including the second information.

    摘要: An apparatus and method for transmitting/receiving a signal in a communication system are provided. A signal reception apparatus of a communication system receives a signal and generates a child Low Density Parity Check (LDPC) codeword vector by decoding the received signal according to a child parity check matrix supporting a first coding rate. The child LDPC codeword vector includes an information vector including A (A≧1) information bits, and when the first coding rate is equal to a coding rate for a case where D (D≧1) parity bits are punctured among B (B≧1)+C (C≧1) parity bits included in a parent LDPC codeword vector generated by encoding the information vector according to a parent parity check matrix supporting a second coding rate, a child bipartite graph corresponding to the child parity check matrix is generated such that a parent bipartite graph corresponding to the parent parity check matrix corresponds to an edge merge scheme.
