In a DCSK (differential chaos shift keying) system implemented with noise suppression, there are three sources of variance: the DCSK signal itself, additive channel noise and the noise suppression scheme. In this paper, a novel DCSK scheme with chaotic polyphase sequence (CPS) is presented to avoid the variance of the DCSK signal itself and decrease the variance for additive channel noise. The simulation results show that the noise performance of the novel DCSK system is slightly degraded in contrast to FM-DCSK for the estimation variance of the noise suppression scheme. However, this design can be implemented easily.
