The error correction code data communication system comprises a transmitter scrambling both non-coded data and coded data and a receiver descrambling both nondecoded data and decoded data using the same code process. The frequency of occurrence of an error correction pulse in a decoder is monitored to set up synchronization for descrambling. This digital communication system is capable of synchronizing a scrambler and a descrambler to each other without the need for a special synchronizing bit, and descrambling a signal without enhancing data errors developed in a transmission path. |
