Abstract:
1. An impulse radio communication device comprising: a short pulse generator configured to change a shape of an impulse to be output; a bandpass filter configured to receive the impulse and output the impulse as a wave packet; an amplifier configured to amplify an output from the bandpass filter; and an antenna configured to output the wave packet, output from the amplifier, as a wireless signal, the short pulse generator includes a control section configured to change the shape of the impulse to be output, in response to an environmental condition of a transmission path for wireless communication, wherein the control section is configured to generate the impulse, the shape of which causes a spectral intensity of the wireless signal of the wave packet to be high, when a transmission path loss is large; and the control section is configured to generate the impulse, the shape of which causes the spectral intensity of the wireless signal of the wave packet to be low, when the transmission path loss is small.
