为了降低CDSK通信方案的误码率,文章结合差分调制和CDSK通信方案的技术,提出差分相关延迟键控(DCDSK)混沌通信方案,并详细推导了该方案的误码率公式。与CDSK通信方案相比较,该方案能够减小信号内部干扰和噪声干扰,提高传输性能;与DCSK通信方案相比较,该方案能够满足带宽利用率和系统稳定性高、误码率低的要求。

In order to reduce the error rate of CDSK communication scheme, this paper CDSK differential modulation and communication technology solutions proposed Differential Correlation Delay Shift Keying(DCDSK) chaotic communication scheme, and a detailed derivation of the formula for the BER program. Compared with CDSK communications scheme, which can reduce signal interference and internal noise interference and improve transmission performance; compared with DCSK communication scheme, which can meet the high bandwidth utilization and system stability, low error rate requirements.
