Abstract
In the differential chaos shift keying scheme (DCSK), as the chaotic signal is not periodic, the energy per bit carried by the chaotic signal is not constant and can only be estimated; this estimation has a non-zero variance that reduces the noise performance of the system. In this paper, a novel DCSK with chaotic polyphase sequences is presented. The estimation problem can be solved efficiently using the properties of chaotic polyphase sequences, and this scheme can be implemented easily
