Abstract :
A novel modulation and demodulation method based on hyper chaos synchronization is proposed in the paper. By utilizing the coupling characteristics between the drive and response terminals of hyper chaos systems, the problem of time delay and additive noise resistance in the wireless channel can be settled. Simulation results show the advantages of this method over conventional chaos shift keying. It has prospective potential in the practical use in wireless communications.
