In the transmission device, a time-shared signal distributed and outputted from the separator 101 and a transmission delay signal while the time-shared signal being delayed by the delay circuit 102 are added and combined by the adder 103, outputted as the transmission adding signal, the transmission adding signal is convolved to the chirp signal by the chirp filter 104 to cause the outputted transmission convolved signal to be modulated by the modulator 105 and then the signal is outputted as the modulation signal. In the signal receiving device, each of the received convolved signal having the modulated signal convolved by the inverse chirp filter 110 with the signal having a characteristic opposite to that of the chirp signal and the received delay signal delayed by the delay circuit 111 is sampled with the samplers 112, 113 so as to output sample signals, these sample signals are added and combined by the adder 114 to output the received adding signal indicating the demodulated receiving signal.
