Abstract
A PCM (pulse code modulation) signal transmission system processes sequentially transferred digital information words including two error correcting words consisting of a parity code word and a b-adjacent code word and adds them to the digital information words, time-interleaves each of the information words and its error correcting words in the block into time-interleave blocks distributed over a predetermined time, adds an error detecting code to at least one of the time-interleaved blocks, and transmits at least one time-interleaved block and error correcting code associated therewith. Method and apparatus for de-interleaving and error correction based on the three appended codes are included.
