摘要： A decoding apparatus generates error position sets of data sequence by generating a codeword from positions of soft input values output from a low reliability position detecting circuit and from syndromes computed by a syndrome calculation circuit. The recording apparatus further includes a codeword candidate generating circuit that computes correlation mismatch amounts by adding soft input values at the error positions contained in the error position sets, and updates the correction information according to the error position sets and correlation mismatch amounts. The decoding apparatus can calculate the soft output values accurately by utilizing the generated codeword candidates efficiently, and reduce the circuit scale by decreasing the amount of computation.

摘要： An error correction encoding method and apparatus, and an error correction decoding method and apparatus are provided without requiring transmission of tail bits. A turbo encoding step (ST41-ST45) and a transmission termination processing step (ST46→ST44-ST47) are included. In the turbo encoding step, a transmission information bit sequence is divided into a plurality of frames. Registers in each recursive systematic convolutional encoder are initialized before turbo encoding of a first frame. After turbo encoding of the first frame is carried out, a second frame and following frames are continuously subjected to turbo encoding without initializing the registers in each recursive systematic convolutional encoder before the turbo encoding of the second frame and following frames. In a transmission termination processing step, tail bits for initializing the registers in each recursive systematic convolutional encoder are calculated only after a final frame has been subjected to turbo encoding.
