【Abstract】 This paper presents the scheme of digital communication using a chaotic carrier.In the transmitter,the bits are mapped to sample functions of chaotic signals emanated from one or more chaotic attractors by modulating phase of excitation term of driven Chua’s circuit.The bits are demodulated by the optimal demodulator that consists of synchronizable chaotic circuits in the correlation receiver.The proposed scheme can be used for transmitting binary signal and be extended for M-ary signal.Finally,the numerical simulation results demonstrate the proposed scheme effectiveness.更多还原
