Abstract
An error-control system for a continuous ARQ system, wherein, when a transmitter detects a dummy signal different from a negative acknowledgment signal caused by a channel noise appearing on a transmission channel, the transmitter supplies a receiver with a block signal comprising a designating number of a given block, a block data thereof and a check code formed by reversing a prescribed error detection code, thereby controlling the occurrence of an error in data transmission between the transmitting and receiving sides.
