PROBLEM TO BE SOLVED: To provide super-wideband communication technology with which influences upon other radio waves can be reduced in comparison with the case of impulse communications.;SOLUTION: On the side of a transmitter 11, transmitting data are spread-modulated to a wideband signal of a form of temporally continuously transmitting a number of carriers by a spreading modulator 111, and the spread modulated signal is amplified by a transmission amplifier 112 to be transmitted by a cable or by radio while keeping it as a baseband signal. On the side of a receiver 21, the received spread modulated signal is amplified by a reception low gain amplifier 121 and then demodulated by a despreading demodulator 111, the demodulated signal is amplified into a signal with an amplitude of a fixed level by an automatic gain control amplifier 123 of a wide dynamic range, and this signal is discriminated by a discriminator 125 to reproduce data.;COPYRIGHT: (C)2004,JPO&NCIPI
