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.

摘要： A location awareness system using RFID and a wireless communication apparatus for the location awareness are provided. The location awareness system includes a RFID tag, a wireless communication apparatus for location awareness, more than three anchors, a coordinator, and a server. The wireless communication apparatus identifies the target object with the RFID attached through communicating with the RFID tag. The anchors receive information about the identified target object and measuring a distance by communication with the wireless communication apparatus using a predetermined wireless communication scheme. The coordinator collects the measure distance and the information from each of the anchors. The server calculates a location of the target object by receiving information about the measured distances and the target objects from the coordinator and calculating the location of the wireless communication apparatus using the received information.

Also, a mixer mixes the first signal from the first signal generator with the second signal from the second signal generator to generate a chaotic signal having a sum frequency of the first and second signals and the harmonic waves of the first and second signals. A filter passes a signal of a preset band out of the chaotic signal from the mixer.
