Abstract

The invention relates to a chaotic signal transmitter using a pulse shaping method to amplitude-modulate a chaotic signal according to a transmission signal, thereby transmitting the chaotic signal having various slopes. The chaotic signal transmitter includes a waveform converter for blocking high frequency component of the transmission signal to convert the waveform of the transmission signal and a chaotic signal generator for generating the chaotic signal. The chaotic signal transmitter further includes a modulator for amplitude-modulating the chaotic signal according to the waveform-converted transmission signal.

a chaotic signal generator for generating a chaotic signal; and

a modulator for amplitude-modulating the chaotic signal from the chaotic signal generator according to the waveform-converted transmission signal from the waveform converter.

2. The chaotic signal transmitter according to claim 1, further comprising:

a band pass filter for passing the chaotic signal modulated by the modulator through a predetermined band; and

an amplifier for amplifying the band-passed chaotic signal from the band pass filter into a predetermined magnitude.

3. The chaotic signal transmitter according to claim 1, wherein the modulator comprises a mixer for mixing the transmission signal waveform-converted by the waveform converter and the chaotic signal from the chaotic signal generator to amplitude-modulate the chaotic signal.

4. The chaotic signal transmitter according to claim 1, wherein the waveform converter blocks a high frequency component of the transmission signal to convert the waveform of the transmission signal.

5. The chaotic signal transmitter according to claim 4, wherein the waveform converter comprises a low pass filter.
