Dual-system transmitting device and receiving device

摘要

A dual-system transmitting device comprising a chaos signal generator 31; a band-pass filter 32 that filters the generated chaos signal into a signal within an information transmission bandwidth preset in a transmission side; an impulse signal generator 33; a switching element 34 that selectively outputs the chaos signal passing through the band-pass filter and the generated impulse signal; an amplifier 35 that amplifies the signal selected by the switching element; and a signal transmitting unit 36 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. Also 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.
