| 摘 要： | 目前各种混沌键控调制方案中，混沌差分键控（DCSK）有着最优的抗噪性能。主要研究混沌DCSK调制在加性高斯白噪声（AWGN）信道和两径瑞利衰落延时信道（two—ray Rayleigh fading channel with delay）的误码率公式，并对其误码率特性进行相应的仿真和分析，最后再与CSK系统的性能做比较。

| Abstract: | This paper presents the performance of non-coherent DCSK communication system over AWGN channel and two-ray Rayleigh fading channel.Analytical expressions of the bit error rates are derived under the AWGN and two-ray Rayleigh fading channel with delay model.Analytical and simulated results are presented and compared.The multi-path performance of the DCSK system is also compared with that of the coherent CSK system at last. |
