Abstract: PURPOSE:To improve an SN ratio and to prevent the number of times of resending from being increased even in a transmission line with a low SN ratio to improve the efficiency of transmission by synchronously adding a resending signal to an initial sending signal. CONSTITUTION:A transmitter 2 executes the error detectable coding, modulation, amplification, etc., of a signal generated from a data source 1 and sends the processed signal to a transmission line 3 and temporarily stores data outputted from the data source 1. An error detector 10 detects the error of a code demodulated by a deciding device 9, and at the time of detecting the error, sends a resending acknowledgment(NACK) to the transmitter 2 through a transmission line 13. At the time of receiving the NACK, the transmitter 2 resends the same data as the temporarily stored ones. At the time of sending the NACK, a gate circuit 7 is controlled so as to be turned on. Thereby, the receiving waveform of the resent data are A/D converted and the digital data are synchronously added to the waveform of the data previously received and stored in a memory 8 by adder 6. The synchronously added signal is sent and processed to/by the deciding device 9 and its SN ratio can be improved by about 3dB at the one synchronous addition.
