摘要

摘要: 该文提出一种名为无信号内干扰相关延迟键控(Correlation-Delay-Shift-Keying with No Intrasignal Interference, CDSK-NII)的新型混沌通信方案。采用重复混沌序列为参考信号，同时利用零和序列确保参考信号与信息信号严格正交，CDSK-NII能够在解调过程中消除信号内干扰。在高斯白噪声信道和Rayleigh衰落信道中分析CDSK-NII的比特误码率。实验结果表明：由于无信号内干扰，CDSK-NII的比特误码率低于CDSK和通用相关延迟键控(GCDSK)；随着复帧长度的增加，CDSK-NII的性能将进一步提升，比特误码率低于参考自适应相关延迟键控(RA-CDSK)。

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).
