MODULATION AND DEMODULATION CIRCUITS OF CHAOS FREQUENCY TRANSITION

摘要

The present invention relates to a chaotic frequency shifting and demodulation circuit, by using a combination synchronization and driving synchronization at the same time, simply configure a demodulation circuit in a secret communication circuit and detect the correct output signal to improve the S / N ratio This is to provide a chaotic frequency shifting and demodulation circuit suitable for implementing perfect confidential communication.;The chaotic frequency shifting and demodulation circuit of the present invention has a chaotic modulation circuit unit consisting of a plurality of chaotic circuits for generating a multiplication frequency signal without changing its inherent characteristics and modulating a transmission information signal to transmit the chaotic carrier, and the chaotic modulation. And a demodulation circuit unit for simultaneously detecting a transmission information signal from a carrier wave transmitted from the circuit unit.
