摘要： Provided is a dual-system transmitting device comprising a chaos signal generator that generates a chaos signal; a band-pass filter that filters the generated chaos signal into a signal within an information transmission bandwidth preset in a transmission side; an impulse signal generator that generates an impulse signal synchronized with a transmitted signal; a switching element that selectively outputs the chaos signal passing through the band-pass filter and the generated impulse signal; an amplifier that amplifies the signal selected by the switching element; and a signal transmitting unit that transmits the signal amplified by the amplifier through an antenna. When the signal amplified by the amplifier is a chaos signal, the signal transmitting unit modulates the amplified signal through an OOK (on-off keying) scheme such that the signal is transmitted as a carrier of a transmitted signal. When the signal amplified by the amplifier is an impulse signal, the signal transmitting unit passes the signal to transmit.Provided is a dual-system receiving device, which is applied to both a received signal using a chaos signal as a carrier and a received signal using an impulse signal as a carrier, the dual-system receiving device comprising a band-pass filter that filters a received signal into a signal within an information transmission bandwidth preset in a reception side; an amplifier that amplifies the filtered received signal; a first demodulator that, when the amplified received signal is a received signal using a chaos signal as a carrier, demodulates the amplified received signal; a second demodulator that, when the amplified received signal is a received signal using an impulse signal as a carrier, demodulates the amplified received signal; and a switching element that selectively outputs the received signal amplified by the amplifier to the first or second demodulator.
