Abstract
In the concatenated coding data compensation communication system, the coding and decoding are performed in a differential coder and a differential decoder. 2-channel output obtained after coding is parallel-to-serial converted and then subjected to synonym insertion before being transmitted. On the receiving side, the received data is supplied after detection and removal of sync-words in a Viterbi decoder, and the decoder is operated on the basis of the timing of detection of the detected sync-words.
