摘要: 該文提出一種名為無信號內(nèi)干擾相關(guān)延遲鍵控(Correlation-Delay-Shift-Keying with No Intrasignal Interference, CDSK-NII)的新型混沌通信方案。采用重復(fù)混沌序列為參考信號，同時利用零和序列確保參考信號與信息信號嚴格正交，CDSK-NII能夠在解調(diào)過程中消除信號內(nèi)干擾。在高斯白噪聲信道和Rayleigh衰落信道中分析CDSK-NII的比特誤碼率。實驗結(jié)果表明：由于無信號內(nèi)干擾，CDSK-NII的比特誤碼率低于CDSK和通用相關(guān)延遲鍵控(GCDSK)；隨著復(fù)幀長度的增加，CDSK-NII的性能將進一步提升，比特誤碼率低于參考自適應(yīng)相關(guān)延遲鍵控(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). -
