    • 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.
    • 提供纠错编码方法和装置以及纠错解码方法和装置,而不需要传输尾比特。 包括turbo编码步骤(ST 41 -ST 45)和发送终止处理步骤(ST 46-> ST 44 -ST 47)。 在turbo编码步骤中,发送信息比特序列被分成多个帧。 每个递归系统卷积编码器中的寄存器在第一帧的turbo编码之前被初始化。 在执行第一帧的turbo编码之后,在第二帧和后续帧的turbo编码之前,第二帧和后续帧被连续地进行turbo编码,而不在每个递归系统卷积编码器中初始化寄存器。 在传输终止处理步骤中,仅在最后一帧已进行turbo编码之后才计算用于初始化每个递归系统卷积编码器中的寄存器的尾比特。
