摘    要:针对相关延迟键控(CDSK)混沌通信方案存在的缺点,提出了一种改进的混沌键控调制方案——分段移位相关延迟键控(SSCDSK)。作为一种多进制调制方案,SSCDSK将延迟信号等分成M个信号段,根据传送的M进制数字码元,将M个信号段循环右移n(0≤n
关 键 词:混沌通信  相关延迟键控  分段移位  误码率

Abstract:To overcome the disadvantage of correlation delay shift keying(CDSK) based chaotic communication scheme,an improved chaotic communication method is proposed using chaos-Segment Shift Correlation Delay Shift Keying(SSCDSK).As a multilevel modulation scheme,the delayed signal of SSCDSK is divided into M parts followed by shifting n segments out of M segments rightward circularly(02M times higher than that of CDSK under the condition of the same length of chaotic signal.
Keywords:chaotic communication  CDSK  segment shift  bit error rate
