| 摘要 |
The present invention relates to a Viterbi decoder and a Viterbi decoding method in a register exchange method. The Viterbi decoder receives an encoded bit sequence of a convolutional encoding method from a channel, generates an expanded encoded bit sequence by cyclically adding a part of the encoded bit sequence or the entire encoded bit sequence to the encoded bit sequence more than one time, performs a Viterbi decoding operation in a register exchange method, and generates decoded data. In addition, the Viterbi decoder selects an end bit sequence corresponding to the number of the unit of encoded bits among the decoded data, rearranges an order of the end bit sequence, and generates final decoded data.
