Concatenated block and convolution encoder-decoder. |
摘要 |
<p>Disclosed is an error correction coding and decoding apparatus carrying out block decoding of coded information data on the basis of a generator polynomial. On the side of a transmitting station (18), each frame of information data is coded into a block coded data by a block encoder (19) by the use of a generator polynomial G(x), and, after adding a tail bit to the coded data, the data is coded by a convolutional encoder (20) into a convolutional coded data and transmitted. On the side of a receiving station (22), the received convolutional coded data is decoded in a Viterbi decoder (24) in a reverse order by means of trace back, and the decoded data is then subjected to block decoding by a block decoder (25) by the use of a reciprocal polynomial G'(x) that is the reciprocity of the generator polynomial G(x) used in the block encoder, thereby minimizing an undesirable processing delay due to the trace back.</p> |
