ABSTRACT:
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.
