为了提高差分混沌移位键控（DCSK）可获得的数据速率，本文提出了参考移位差分混沌移位键控（RS-DCSK）调制方案。通过使用DCSK中每个混沌参考样本的精确副本和移位版本作为消息载体，可以在一个数据调制样本序列中携带两位数据。理论分析和仿真结果表明，与DCSK相比，RS-DCSK可以实现双倍可达数据率（带宽效率）、无特征频谱、大大提高通信安全性和更好的误码率（BER）性能。
To increase the attainable data rate of differential chaos shift keying (DCSK), reference-shifted differential chaos shift keying (RS-DCSK) modulation scheme is proposed in this paper. By using both the exact replica and the shifted version of every chaotic reference sample in DCSK as message bearers, two bits of data can be carried in one data-modulated sample sequence., Theoretical analysis and simulation results show that RS-DCSK could achieve doubled attainable data rate (bandwidth efficiency), featureless frequency spectrum, greatly increased communication security and even better bit error rate (BER) performance in comparison to DCSK.
