    • The coding apparatus, coding processing target sequence forming method and Viterbi decoding apparatus of the present invention can realize low delay processing with a minimum number of repetitive processing and suppress the degradation of the accuracy of decoding at the ends of a decoded sequence due to truncation error. In the coding apparatus mounted on the transmitting apparatus (100), a control information rearranging section (130) receives as input a control information sequence, in which a plurality of control information blocks are arranged in a predetermined order, and forms a coding processing target sequence by rearranging the order of the plurality of control information blocks to form an assembled sequence grouping control information blocks comprised of predictable bit sequences in the plurality of control information blocks, and to allocate the assembled sequence to a predetermined position in the control information sequence. Further , an encoding section (140) encodes the coding target sequence using the tail-biting convolutional coding scheme.
    • 本发明的编码装置,编码处理对象序列形成方法和维特比解码装置可以以最小数量的重复处理实现低延迟处理,并且抑制由于截断误差导致的解码序列的末尾的解码精度的劣化 。 在安装在发送装置(100)上的编码装置中,控制信息重排部(130)接收作为输入的控制信息序列,其中以预定顺序排列多个控制信息块,并形成编码处理对象 通过重新排列多个控制信息块的顺序来形成由多个控制信息块中的可预测位序列构成的组合序列分组控制信息块,并将组合序列分配到控制信息序列中的预定位置。 此外,编码部(140)使用尾巴卷积编码方式对编码对象序列进行编码。
