摘    要:差分混沌键控(DCSK)是一种非相干调制技术,其输出信号具有固有的宽频特性。在各种混沌键控数字调制方案中,DCSK调制有着最优的抗噪声性能。文中在文献[4]的基础上,进一步分析了DCSK在瑞利衰落信道下的系统性能,推导出误码率公式,并通过计算机仿真实验验证了该理论分析的正确性。

关 键 词:差分混沌数字键控  瑞利衰落  误码率

Abstract:The differential chaos shift keying (DCSK) is a non-coherent modulation technique,and its output signal has the inherent wide-frequency characteristic. The performance of DCSK is the best one various in chaotic digital modulation schemes. On the basis of reference4,the system performance is analyzed and the expressions of the bit error rates are derived for DCSK over Rayleith fading channel. And logistic map with zero mean is used for chaos generation in simulation.
Keywords:differential chaos shift keying  rayleigh fading  bit error rate
