Abstract
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.
