Abstract This paper proposes a novel chaotic communication scheme named Correlation-Delay-Shift-Keying with No Intrasignal Interference (CDSK-NII). By utilizing the repeated chaotic sequence as the reference signal and taking advantage of the zero-sum sequence to ensure the reference signal strictly orthogonal to the information- bearing signal, CDSK-NII can eliminate the intrasignal interference during the demodulation. The Bit Error Ratio (BER) of CDSK-NII is analyzed under AWGN channel and Rayleigh fading channel. Experiment results show that, due to no intrasignal interference, the BER of CDSK-NII is lower than that of CDSK and Generalized CDSK (GCDSK); with the length of multiframe increasing, the performance of CDSK-NII becomes better, and its BER is lower than that of Reference-Adaptive CDSK (RA-CDSK).
