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.

摘要： A multiple coding apparatus comprises a first encoder for encoding a plurality of input sequences in parallel so as to generate a plurality of output coded sequences in parallel while adding an error-correcting bit sequence to each of the plurality of input sequences. An interleaving circuit interleaves the plurality of output coded sequences applied thereto in parallel from the first encoder without having to use any memory. The interleaving circuit permutes the plurality of input sequences on a bit-by-bit or symbol-by-symbol basis so as to generate a plurality of interleaved coded sequences in parallel. A second encoder then encodes the plurality of interleaved coded sequences applied thereto in parallel from the interleaving circuit so as to generate a plurality of output coded sequences in parallel while adding an error-correcting bit sequence to each of the plurality of interleaved coded sequences.
