摘要 |
In a communication system having a transmission station which transmits the datasignal and a receiving station which receives the data signal, the transmission station consists of an adding means for adding an error detecting code showing a position of a transmission error, which occurs on said data signal, in said data signal to said data signal and a retransmission means for retransmission of a part in said data signal when said receiving station requests the retransmission of the part in said data signal. The receiving station consists of a judgment means for judging a position of the transmission error in said data signal on the basis of the error detecting code which is added by the adding means and a request means for requesting the retransmission of the part containing the transmission error in the data signal on the basis of the position of the transmission error.
