摘要
为了安全、可靠、有效地传送UWB信号,本文提出了采用蔡氏混沌电路对UWB信号进行加密的技术进行信号的传送,文中首先设计产生可行的UWB信号的电路,然后找到合适的蔡氏混沌电路,最后将二者进行合成。仿真结果表明,蔡氏混沌电路可以有效地将UWB信号进行加密,如果在再进行调制与解调电路和抗干扰电路,信号的保密性会更好。
In order to transmit UWB signal safely, reliably and efficiently, this paper proposes a new method for cryptographic UWB signal transmission using chua's chaotic circuit. first,this paper designs feasible UWB signal circuit, and then find a suitable chua's chaotic circuit, finally synthesize the both circuits. Simulation results show that chua's chaotic circuit can encrypt the UWB signal effectively, if the circuit has modulation and demodulation circuit and anti-jamming circuit, confidentiality of the signal will be better.
