Radio frequency communication devices using chaotic signal and method thereof
First Claim
1. An RF (radio frequency) communication system comprising:
- a transmitter terminal which generates a chaotic signal comprising a plurality of frequency components in a predetermined frequency band and transmits a chaotic carrier generated by synthesizing a data signal with the chaotic signal to a receiver terminal; and
the receiver terminal extracts the data signal from the chaotic carrier received from the transmitter terminal via a wireless network.

Abstract
RF (radio frequency) communication devices which use a chaotic signal and a method thereof are provided. An RF communication system includes: a transmitter terminal which generates a chaotic signal including a plurality of frequency components in a predetermined frequency band and transmits a chaotic carrier generated by inserting a data signal including information to be transmitted into the chaotic signal to a receiver terminal; and the receiver terminal extracts the data signal from the chaotic carrier received from the transmitter terminal via a wireless network and outputs the extracted data signal. As a result, low power, light weight local area RF communication devices can be realized.
