Abstract
A tail-biting decoding method and device are provided, so as to improve accuracy of backtracking state determination and decrease decoding delay. The method includes the following steps. Survivor paths of a training system are acquired. The training system is formed of a first transport block and a second transport block connected in series. The number of the survivor paths passing through each first state of the second transport block is counted. A first state having a maximum number of the survivor paths may be selected as a backtracking state of the second transport block. Backtracking decoding is performed on the second transport block by using the survivor paths on the backtracking state, so as to obtain a decoding result.
