Multiuser Multicarrier Chaotic Differential Communication System Based on Cooperative Model

To improve the antifading and inter-code interference ability of the noncoherent chaotic communication system, a multiuser multicarrier chaotic differential communication system based on a cooperative model is proposed. A single relay of the decode-and-forward type is investigated according to the conventional cooperation protocol. Independent three path Rayleigh channels are considered, and the bit error rate and outage probability are derived and verified via simulations. Numerical and Monte Carlo simulations show that the proposed model can effectively deter fading and inter-code interference effectively.
