Abstract :
This paper proposes a new noncoherent detection system improved based on the differential chaos shift keying (DCSK) and the correlation delay shift keying (CDSK). In this scheme, a transmitter changes chaotic maps for generating a chaotic sequence efficiently depending on an initial value. Also, the proposed method can choose the chaotic map by a very simple algorithm. In order to investigate the proposed method, computer simulations were carried out and observe the performance.
